Answer:
A 1 kg block sliding to the right on a level, frictionless surface with a speed
of 2 m/s collides and sticks to a second 1 kg block sliding to the left. After
the collision, the blocks are motionless. What was the speed of the second
1 kg block before the collision?
C ,because kinetic energy is stored and there is energy needed for the ball to keep bouncing
ΔPE = mgh₂ - mgh₁= mg(h₂- h₁) = mgΔh
