Question
Throwing a ball at a wall:
Trial 1: You throw a ball of mass m_1 at a brick wall with a velocity of 20 m/s. It hits the wall
and bounces back with a velocity of 10 m/s.
Trial 2: You throw a ball of the same mass (m_1) at a brick wall with a velocity of 40 m/s. It hits
the wall and bounces back with a velocity of 35 m/s.
