A Block of Mass 5 Kg Slides Down a Frictionless

Multiple Choice

A block of mass 5 kg slides down a frictionless track from a height of 1.5 m. It collides with a second mass of 8 kg. The two blocks stick together and after the impact they begin to slide on a rough surface with a coefficient of kinetic friction of 0.65 until coming to rest. Calculate how far, d, the blocks slide on the rough surface.

A) 3.4 m
B) 0.22 m
C) 2.3 m
D) 0.34 m
E) 0.16 m
