Question

A box of mass m₁ smoothly

slides from rest a distance.

L down an incline at an

angle, and on the flat

section collides with another box of mass m₂. After the collision, the second box

travels a distance d into a rough section (kinetic

friction coefficient NK) before stopping, as shown.

a) Find d for an elastic collision.

b) Find d for a completely inelastic collision ("sticky boxes").

c) Compute the ratio of the distances found in parts (a) and (b)
