A 100 g ball moving with a velocity of 20 m/s returns in opposite direction with a velocity of 30 m/s after striking a bat. Find the impulse.
Let the final direction of velocity be positive.
Mass of the ball, m = 100 g = 0.1 kg
Initial velocity of the ball, u = -20 m/s
Final velocity of the ball, v = 30 m/s
Impulse experienced by the ball is equal to its change in momentum.
