A ball of mass m = 1 kg rolling without slipping strikes a wall and rolls back. Before the impact the velocity of the ball was 10 cm/s and after the impact 8 cm/s. The amount of heat evolved during the impact (assuming no loss of heat) is
- \(2 \times 10^{-4} \downarrow\)
- \(36 \times 10^{-4} \downarrow\)
- \(18 \times 10^{-4} \downarrow\)
- zero
Answer
(C) 18 10^ -4
