1. A 2 kg block is on a ramp, and slides down the ramp. The ramp has angle 30 degrees with

respect to the ground and moves the block at a constant velocity. The block has a

displacement vector with a magnitude of 6 m. What is the work done on the block by thefrictional force?

2. A 0.2 kg block is on a ramp. The ramp has an angle of 30 degrees with respect to the ground. The block compresses a spring with a spring constant of 40 N/m a distance of 1 m. What is the maximum magnitude of displacement on the block? You can ignore friction.
