Given
The initial velocity of of ball = u = 15 m/s
Final velocity of ball = v = 0
Time taken to stop the ball = t = 0.018 s
Mass of the ball = 0.59 kg
Therefore acceleration = a = (u - v)/t = -15/0.018 m/s^2
and force f = m*a = 0.59 (-15/0.018) = 491.6666 N approximately
Answer: force exerted on the receiver is 491.6666 N.
