Answer:

The car is decelerating because speed is decreasing and you also get the answer in negative

Explanation:

acceleration= change in speed(final speed-initial speed)/time

final speed=40km/h

initial speed=60km/h

40-60/0.4

-20/0.4= -50km/h^2

When the displacement of a 500 g mass, undergoing simple harmonic motion, is defined by the function :  x=-3.5sin(π/2t+(5π)/4).The maximum potential energy is 7.56J

Simple harmonic motion, or SHM, is a particular form of periodic motion of a body that results from a dynamic equilibrium between an inertial force that is proportional to the body's acceleration away from the static equilibrium position and a restoring force on the moving object which is directly proportional to the magnitude of the object's displacement and applies towards the object's equilibrium position.

Given :

k = 1.234N/m

x=3.5

Now by applying the value of spring constant, we can find the maximum potential energy.

PE=[tex]\frac{1}{2} kx^{2}[/tex]

PE=1/2*1.234*3.5^2

PE=7.56J

Hence, The maximum potential energy is 7.56J

The complete question is :

The displacement of a 500 g mass, undergoing simple harmonic motion, is defined by the function :

x=-3.5sin(π/2t+(5π)/4)

Find maximum potential energy.

The value of the mystery displacement is 8.74 m. We can find it by dividing the force value with the work that was done to the object.

As per given data are work(W) = 376 J and Force(F) = 43 N, we can use a formula that contain correlation between work and force. The formula is W = F * Δx where   Δx is displacement value. Hence, in order to find the value of displacement, the calculation will be:

W = F * Δx

376 = 43 * Δx

The amount of work done by a box that is pushed 9 meters across a horizontal floor by a force of 3000N is 27000J.

Work in physics refers to the measure of energy expended in moving an object; most commonly, force times distance.

It is said that no work is done if the object does not move. The work done on an object can be calculated by multiplying the force of the object by its distance as follows:

W = F × d

W = 3000N × 9m

Work done = 27,000J

Therefore, 27,000Joules is the work done on the box.

Balanced force does a window washer want acting on him when trying to keep the same position.

What is force?
Force is an external influence that is capable of changing the motion of a body, either by a push or pull, or by causing a change in the shape or direction of the body. Force is a vector quantity, meaning it has both magnitude and direction. It can be a result of either physical contact, like pushing or pulling, or a non-contact force, such as gravity, magnetism, or electricity. Force is a fundamental concept in physics and its effects are studied in numerous fields, from mechanics to thermodynamics. Force can be used to move objects, cause objects to change shape, or cause objects to accelerate. It is a powerful tool for understanding physical phenomena.

If the reactions were successful then we can see the reactions involved O-H groups of the alcohols then the O-H stretching will not be observed in the product.

Analysis of IR spectrum of 1-butanol:

There are sp3 C-H stretching and CH2 bending modes at 2900 and 1500 cm-1 and there is a C-O stretching mode near 1050 cm-1. There is a very large peak around 3400 cm-1. O-H peaks are usually very broad due to H -bonding.The rounded shape  O-H stretching modes occurs because of hydrogen bonding between different hydroxy groups.

Because protons are shared to varying extent with neighboring oxygens, the covalent O-H bonds in alcohol all vibrate at slightly different frequencies and show up at slightly different positions in the IR spectrum.

Instead of seeing one sharp peak, the entire range is observed as a whole lot of them merged into one broad peak. Since C-H bonds don't hydrogen bond very well, hence this phenomenon is not observed for C-H stretching.

Answer:

Explanation:

The net force is sum of all forces when considering in a one-dimensional motion. Since each people pull the object 200 N then that means 5 people together would pull 5 × 200 N = 1000 N.

Therefore, the net force is 1000 N

The speed of the chain at this instant is 8.47 m/s. The change in energy of the chain is 204.8J. The increase in thermal energy of the chain is 25.6J.

Acceleration(a) of Centre of mass = F/m = 64/5 = 12.8 m/s2

a) v2 = u2 + 2as,....(1)

v is final velocity of centre of mass,

u is the initial velocity of centre of mass,

s is the displacement of centre of mass

s = d - L/2 = 3.2 - 0.4 = 2.8m

using equation 1,

V = [tex]=\sqrt{2as} =\sqrt{2*12.8*2.8}=8.47 m/s.[/tex]

Therefore, the speed of the chain at this instant is 8.47 m/s.

2. Change in energy = Total Work Done = Force*Displacement of point on which force is applied = 64*3.2 = 204.8J

Therefore,  the change in energy of the chain is 204.8J

3. Change in Thermal Energy = Change in Energy - Change in Kinetic Energy = 204.8 - 0.5*m*v2

Change in Thermal Energy = 204.8 - 0.5*5*8.47*8.47 = 25.6J

The distance travelled by Hulk is calculated as;

d = ( 6.32 x 10⁴ x 26² ) / ( 2 x 2.43 x 10⁵ )

The speed of the combined train cars after they couple cannot be determined from the information given. The velocity of an object is determined by its speed in a given direction, but it is not specified in which direction the train cars are moving.

Additionally, the concept of momentum must be considered to calculate the final velocity of the combined train cars.

The principle of conservation of momentum states that the total momentum of a closed system (in this case the train cars) remains constant unless acted upon by an external force. Therefore, we would need to know the initial momentum of each train car and the external forces acting on the system in order to calculate the final velocity of the combined train cars.

In trial 1, the speed of the center of mass does not change, while in trial 2, the speed of the center of mass decreases.

In trial 1, the carts collide elastically, which means that the total kinetic energy of the system is conserved during the collision. The two carts will bounce off each other with the same kinetic energy that they had before the collision. Since the center of mass is a point of reference for the total kinetic energy of a system, and its speed is related to its kinetic energy, the speed of the center of mass does not change during the collision. The final kinetic energy of the two-cart system after the collision is the same as the initial kinetic energy. The two carts will move away from each other with the same speed they had before the collision.

In trial 2, the collision is inelastic, which means that some of the kinetic energy is converted into internal energy, this causes the total kinetic energy of the two-cart system to decrease. Since the center of mass is a point of reference for the total kinetic energy of a system, and speed is related to kinetic energy, the decrease in total kinetic energy causes a decrease in the speed of the center of mass. As the carts stick together after the collision, the final speed of the two-cart system is lower than the initial speed. The final speed of the two-cart system after the collision is slower than the initial speed of the first cart.
