A block of mass 2.95 kg
slides down a 30.0 ∘
incline which is 3.60 m
high. At the bottom, it strikes a block of mass 6.95 kg
which is at rest on a horizontal surface. (Assume a smooth transition at the bottom of the incline.) (Figure 1)


Part A
If the collision is elastic, and friction can be ignored, determine the speed of the block with mass 2.95 kg
after the collision.
