The potential energy (Ep) is 490 J and the velocity is 9.9  m/s.

To calculate the potential energy (Ep) of an object with mass M at a height h above a reference point, you can use the formula:

Ep = M * g * h

where,

g =the acceleration due to gravity (approximately 9.8 m/s² on the surface of the Earth).

M = mass

h = height

For this case:

Ep = 10 kg * 9.8 m/s² * 5 m

Ep = 490 J

To calculate the velocity (v) of an object in free fall, you can use the formula:

v = [tex]\sqrt{2gh}[/tex]

So in this case:

v = [tex]\sqrt{2 * 9.8 m/s^{2} * 5 m }[/tex]

v = 9.899 m/s

v ≈ 9.9 m/s

Note: These formulas assume that the object is in free fall and that there is no air resistance or other forces acting on the object.

The momentum of an isolated system before and after a collision must equal each other, according to the law of conservation of momentum.

The only thing that happens when two bodies collide is that their momentum changes. Thus, for bodies colliding, changes in momentum are always equal and opposite. The momentum of the other body must decrease by the same amount if the momentum of the first body increases. As a result, momentum always remains constant.

Regardless of the type of collision, momentum is always conserved. Although mass is conserved regardless of the type of collision, an inelastic collision may cause the mass to deform, leading to the two possibilities.

The work done by the system is -2.655KJ. This states that the system performs 2.655KJ of work on the surroundings. Thus, the correct option is D.

Work done is defined as the product of force and the distance over which the force is applied on the object. Work is done when a force is applied to an object and the object experiences motion through a distance.

Given that the work is done on the surrounding, i.e., the work is done by the system and the heat is absorbed by the system.

Therefore,

ΔU = -5.155KJ

q = 2500J = 2.5KJ

Now from first law of thermodynamics,

ΔU = q + w

-5.155 = 2.500 + w = -2.655KJ

w = -2.655KJ

Hence the work done is -2.655kJ.

Ice crystals that form by accretion are fairly large, they fall slowly because of there high surface area to volume ratio, which cause high air resistance.

Ice crystals that form by accretion are large and have a high surface area to volume ratio. This high surface area causes more air resistance, which slows their fall. The larger the surface area, the more air resistance there is, and the slower the crystals fall. Additionally, the shape of the crystals can also affect their fall speed, with more irregular shapes experiencing more air resistance and thus falling slower. Ice crystals are the building blocks of snowflakes and have a well-defined and ordered internal structure. The structure of an ice crystal depends on the conditions under which it forms, such as temperature and humidity. At very cold temperatures, the crystals are usually simple hexagonal structures, while more complex branching structures can form at warmer temperatures.

Horizontal equilibrium T sinθ = m x v²/r

r = D/2 = 10.8/2 = 5.4 m

From the above two equations, mg tanθ = m x v²/r

The force required to tip the cube is equal to the coefficient of static friction times the weight of the cube.

fx=μs * 87 kg * 9.8 m/s^2

Generally, The cube will start to tip when the net torque about the point of contact between the cube and the floor is equal to zero. The torque is given by:

torque = force x distance from axis of rotation

The distance from the axis of rotation is half the edge length of the cube (0.475m), and the force is the force applied by the person (). Therefore, the torque is:

torque = fx x 0.475

For the cube to tip, the torque due to the person's force must be greater than the maximum torque the friction can provide, which is the friction force times the distance from the axis of rotation.

The maximum torque provided by friction is:

friction torque = friction force x 0.475

Since the friction force is equal to the normal force (mg) multiplied by the coefficient of static friction (μs), the maximum torque provided by friction is:

friction torque = μs * mg * 0.475

where m is the mass of the cube, g is the acceleration due to gravity and μs is the coefficient of static friction between the cube and the floor.

So, we can find the force needed to tip the cube by equating the torque due to the force with that of the friction torque.

Fx*0.475 = μs * m * g * 0.475

Fx= μs * m * g

Fx= μs * 87 kg * 9.8 m/s^2

Answer: 1200m

Explanation:

Answer: 4m/s2 ✅

Explanation: A vehicle started from rest and its velocity reached 20m/s after 5 seconds. To calculate the acceleration, we can use the formula: acceleration = (change in velocity) / (change in time).

The change in velocity is 20m/s - 0m/s = 20m/s (the final velocity minus the initial velocity)

The change in time is 5 seconds (the time it takes for the velocity to change)

So the acceleration of the vehicle is (20m/s) / (5s) = 4m/s2✅

Answer: The acceleration of the car starting from rest is 4 m/s^2✅

Explanation:

It is an exercise of uniformly varied rectilinear movement.

What will be the acceleration, if a vehicle started from rest and its velocity reached 20 m/s after 5 second?

Data:

a = acceleration = ?

Vo = initial speed = 0

Vf = Final speed = 20 m/s

t = time = 5 s

The formula to calculate the acceleration is a = (Vf - Vo)/t, but it tells us that the car starts from rest, that is, it has no initial velocity, we clear the formula and we are left:

   a = Vf/t

   a = (20 m/s)/5 s
