Question

A 5.2 kg block slides down a 14.1 m long ramp inclined at an angle of 30o above the horizontal. At the bottom of the plane, the block transitions to a flat, smooth table that is 3.3 m in length. There is a spring attached to the wall at the end of the flat portion of the track that has spring constant of 331.9 N/m. What maximum height will the block reach on its return trip?

Answer 1

If there is no friction and no losses in the spring, the block will return to the same height.

$h=14.1\cdot \sin30°=7.05m$
