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 295 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 = 215 kg, what is the magnitude of the acceleration of the 295 kg crate? Assume the rope and pulley are massless.

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 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 group of construction workers are building a house and want to lower down an excess bundle of 2380 kg bricks to ground. They tie one end of a rope to the bundle of bricks, loop it through a pulley, and tie the other end of the rope to a toolbox. If the coefficient of kinetic friction between the toolbox and the floor is 0.650 and the acceleration of the bundle of bricks is 5.71 m/s2, what is the mass of the toolbox? 1.47×104 kg 2.81×103 kg 806 kg 1.76×103 kg

Block A, with mass 15 kg, sits on an incline of 0.53 radians above the horizontal. An attached (massless) string passes through a massless, frictionless pulley at the top of the incline as shown:The coefficient of kinetic friction between block A and the incline is given as 0.32. When the system is released from rest, block B accelerates downward at 1.1 m/s2. What is the mass of block B?Express your answer in kg, to at least one digit after the decimal point.
