Question

A 3kg block slides along a floor with coefficient of kinetic friction k = 0.3, initially moving at 7.0m/s. It travels for 2.0 meters, then encounters a ramp sloped upward at 40o. The ramp also has a coefficient of kinetic friction k = 0.3.

a) How fast is the block moving when it reaches the bottom of the ramp?

b) How far up the ramp does the block slide, before momentarily coming to rest?
