A 6.2 kg mass is placed on a 30 degree incline and is pushed up the incline by a horizontal force of 34 newtons. Determine the acceleration of the mass, in m/s2. Assume that the incline is frictionless. You should assume the the positive direction is up the ramp.
A 2 kg block is placed on a spring of constant 800 N/m at the bottom of a 370 incline so as to compress the spring by 30 cm. Determine how high the block travels after it is released, assuming that the spring imparts all of its energy to the block once they are no longer moving together. Assume that the coe cient of kinetic friction between the block and the incline is 0.375. Please show all the steps.

A 4 kg object starts from rest from the top of a rough 30 degree incline and slides 3.0 m down the incline in 2.0 s. Find the coefficient of friction between the block and the incline. A)0.25 B)0.33 C)0.4 D)0.90
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...
