Please provide a step-by-step solution. Make your explanation easy to understand.

1.) Find the acceleration of an inclined Atwood's Machine. The angle of the inclined plane is 30" from the horizontal. (m1: 1 kg , m2: 5 kg and the coefficient of kinetic friction is 0.25) 2.) Suppose you move the crate by pulling upward on the rope at an angle of 300 above the horizontal. How hard must you pull to keep it moving with constant velocity? The weight of the crate is 500 N. Assume that pi: = 0.40 3.) You push a LOUkg food tray through the cafeteria line with a constant 9.0N force. The tray pushes on a 0.50kg carton of milk. The tray and carton slide on a horizontal surface so greasy that friction can be neglected. Find the acceleration of the trailr and carton and the horizontal force that the tray exerts on the carton
