Let us assume the initial velocity direction of the handball as negative.
Mass of the handball = m = 0.1 kg
Initial velocity of the handball = V1 = -25 m/s
Velocity of the handball after rebounding from the wall = V2 = 19 m/s
Change in momentum of the ball =
P
Change in momentum of the handball = 4.4 N.s

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.
