Expert Answer
Mass of cricket ball is greater than mass of tennis ball. Hence if both are moving with same speed,
cricket ball is having more kinetic energy than tennsis ball.
Hence it is easier to stop tennis ball than cricket ball because less energy is required to stop.
Due to greater mass, change in momentum is more for cricket ball after it is stopped by hand.
The impulsive force produced by the hand to stop the cricket ball is greater in comparison with stopping the tennis ball.
