A 20.0 kg package is positioned at the bottom of an inclined ramp. The ramp has a length of 15.0 m, and an inclination angle of 34.0°above the horizontal floor. A constant force having a magnitude 290 N, and directed parallel to the horizontal floor, is applied to the package in order to push it up the ramp. While the package is moving, the ramp exerts a constant frictional force of 65.0 N on it.

a. Draw a free-body diagram of the package.

b. What is the total work done on the package as it moves from the bottom to the top of the ramp?

c. How much time does it take for the package to get to the top of the inclined plane?

A 35.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.500 and the constant of the spring is k = 6000 N/m. What is the net impulse exerted on...
