In the figure provided, a 300. kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the mass on the left is m = 80.0 kg, what is the magnitude of the acceleration of the 300. kg crate? Assume the rope and pulley are massless. 9.80 m/s2 7.19 m/s2 5.67 m/s2 27.0 m/s2

a 150. kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the mass on the left is m = 55.0 kg, what is the magnitude of the tension of the rope attached to the 150. kg crate? Assume the rope and pulley are massless.

In the figure provided, a 160. kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the crate accelerates at 4.45 m/s2, what is the mass of the block to the left of the pulley? Assume the rope and pulley are massless.

In the figure provided, a crate of mass m sits at rest on a 20° ramp and is connected to another crate of mass 1.80 kg by a rope and pulley. If the coefficient of friction is μk = 0.570 and μs = 0.850 with the surface, what acceleration will the mass m have if it is slightly nudged and begins to be pulled up the ramp? Assume the rope and pulley are massless.

A rocket is attached to a crate with a combined mass of 1330 kg. The crate is launched with 242 N of thrust down a frictionless icy hill sloped at 16.4° from the horizontal. What is the magnitude of acceleration of the crate while it travels down the hill?

John pulls a 50 kg crate with a  force of 215 N to the right. There is a frictional force of 200 N acting to the left, between the crate and the ground. Alan assists John by pushing the crate with a force of  300 N also to the right.What is the acceleration of the trolley in m/s2?
