At t = 0, a wheel rotating about a fixed axis at a constant angular acceleration of -0.40 rad/s2 has an angular velocity of 1.5 rad/s and an angular position of 2.3 rad. what is the angular position of the wheel at t = 2.0 s?

Answers

Answer 1

At t = 0, the wheel has an angular position of 2.3 rad and an angular velocity of 1.5 rad/s.

Since the wheel is rotating about a fixed axis at a constant angular acceleration of -0.40 rad/s2, we can use the equation for angular position to calculate the wheel's angular position at t = 2.0 s.

Angular position = initial angular position + (initial angular velocity × time) + (1/2 ×angular acceleration ×time²)

Angular position at t = 2.0 s = 2.3 rad + (1.5 rad/s × 2.0 s) + (1/2 ×-0.40 rad/s2 × (2.0 s)²)

Angular position at t = 2.0 s = 2.3 rad + 3.0 rad + -1.6 rad

Angular position at t = 2.0 s = 3.7 rad

Seismic-wave velocity can change (increase or decrease) as the waves pass through different rock types.

Answers

Yes, seismic-wave velocity can change as the waves pass through different rock types.

Rocks with high porosity and permeability tend to have lower seismic-wave velocities because the pores contain fluid that can dampen the energy of the seismic waves, while rocks with high compaction and densities tend to have higher seismic-wave velocities. Additionally, changes in temperature and pressure can also affect seismic-wave velocity.

A meter‑long wire of mass 185 g is attached to a 60. 0 Hz mechanical wave oscillator operating at 139 W. The far end of the wire is strung over a frictionless, massless pulley, and a 306 g mass is hung from it. When the oscillator is turned on, it produces a sinusoidal wave in the wire. Calculate the amplitude of oscillation of the wire. Use the value 9. 81 m/s2 for the acceleration due to gravity

Answers

The tension in the wire is 2.99986 N.  The amplitude of the oscillation of the wire is approximately 0.01067 meters.

The tension (T) can be calculated using the equation:

T = m × g

T = 0.306 × 9.81

T = 2.99986 N

The linear mass density (μ) of the wire is given by the mass per unit length of the wire. It is calculated as:

μ = m(wire) ÷ L(wire)

μ = 0.185 ÷ 1

μ = 0.185 kg/m

The speed (v) of the wave on the wire can be determined using the equation:

v = √(T ÷ μ)

v = √(2.99986 ÷  0.185 )

v = 7.351 m/s

The power (P) transmitted by the wave is related to the amplitude (A) and the speed (v) of the wave through the equation:

P = 2π² × μ × v × A² × f²

A² = P ÷ (2π² × μ × v × f²)

A² = 139 ÷ (2π² × 0.185 × 7.351 × (60.0)²)

A² = 1.138 × 10⁻⁴

A = √(1.138 × 10⁻⁴)

A = 0.01067 m

Therefore, The amplitude of the oscillation of the wire is approximately 0.01067 meters.

A 64 g plastic ball is moving to the left at 24 m/s . How much work must be done on the ball to cause it to move to the right at 24 m/s

Answers

The ball requires a total of zero work to go to the right at 24 m/s.

Take into account the ball's kinetic energy.

Vi = -24 ms-1 for the initial velocity

Final velocity: vf = +24ms⁻¹

K = 12mvf²- 12mvi² = 12m(vf² - vi²) = 12m(242 - 242) = 0,

meaning that the ball does not undergo any effort.

As an alternative, think about the effort made to stop the ball.

W1 = ½m(0 – 24²) = 0.5 × 0.06 × –576 = –17.28J

Work required to accelerate the ball from rest to +24 milliseconds per second was W2 = 12m(242 - 0) = 0.5 0.06 576 = +17.28 J.

Therefore, the sum of the work is W = W1 + W2 = -17.28 + 17.28 = 0 J.

two blocks are connected by a string of negligible mass that passes over massless pulleys

Answers

If two blocks are connected by a string of negligible mass that passes over massless pulleys, the system can be analyzed using the principles of Newton's second law and the conservation of energy.

In this scenario, the net force acting on each block is the tension in the string, which is equal in magnitude for both blocks.

Therefore, if the blocks have different masses, they will have different accelerations.

In this scenario, the mechanical energy of the system is the sum of the gravitational potential energy and the kinetic energy of the blocks. If the pulleys are massless and frictionless, then the mechanical energy of the system will be conserved.

In summary, the two blocks will move together with the same acceleration if the pulleys are massless and frictionless.

Answers

The freight car which is being dumped into the metal scrap has the final velocity of 0.18 m/s.

In this problem, we use the principle of conservation of linear momentum.

Given that,

Mass of the freight car m₁ = 30,000 kg

Mass of the hopper m₂ = 110,000 kg

Velocity of the freight car u₁ = 0.85 m/s

Velocity of the hopper u₂ = 0

Let the velocity of the loaded freight car = v

We need to find out v.

m₁ u₁ + m₂ u₂ = ( m₁ + m₂) v

After putting the values into the equation above, we have,

30,000 × 0.85 + 110,000 × 0 = (30,000 + 110,000) v

140,000 v = 25500

Answers

The difference in gravitational potential energy for sputnik 1 as it moved from apogee to perigee is 193 kJ.

The gravitational potential energy of an object in orbit around the Earth can be calculated using the equation:

U = -GMm/r

where U is the gravitational potential energy, G is the gravitational constant, M is the mass of the Earth, m is the mass of the object.

The difference in gravitational potential energy as the satellite moves from apogee to perigee can be found by calculating the potential energy at each point and subtracting the two values:

U(apogee) = -(6.67 x 10^-11 N*(m^2)/(kg^2)) * (5.972 x 10^24 kg) * (83.5 kg) / (7300 x 10^3 m)

U(perigee) = -(6.67 x 10^-11 N*(m^2)/(kg^2)) * (5.972 x 10^24 kg) * (83.5 kg) / (6610 x 10^3 m)

U(apogee) = -1.865 x 10^5 J

U(perigee) = -2.058 x 10^5 J

The difference in gravitational potential energy is:

= U(perigee) - U(apogee)

= -2.058 x 10^5 J - (-1.865 x 10^5 J)

= 193 x 10^3 J

Rp => [tex]\frac{1}{7} + \frac{1}{1} = \frac{1+7}{7} = \frac{8}{7} \\[/tex]

Rp = [tex]\frac{7}{8}[/tex] = 0.875

4 + 0.875 + 9 = 13.875Ω

in the second diagram:-

R= Rp + Rs + Rp'

Rp => 1/6 + 1/3 = 1+2/6 = 3/6 => 2

Rp' => 1/3+1/3+1/3 = 3/3 => 1

R = 2 + 2 + 1 = 5 Ω

What is the acceleration of the particle at t 0?

Answers

The acceleration of the particle at t=0 is zero because the particle is in rest position and did not moving at any of the instance or travelling at an uniform speed through out the whole journey or yet did not start from the source point.

Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction. Acceleration of the body that we can consider is the increasing value of the velocity of any object at a constant rate and that of wee can calculate. Hence by the primary information that we have we can formerly consider that the acceleration which is acting on the particle at t=0 is zero because the particle is in rest position and did not moving at any of the instance or travelling at an uniform speed through out the whole journey or yet did not start from the source point.
