A .15kg rubber ball is bounced off a wall. Before hitting the wall, the ball moves toward the wall at a velocity of (-8,1) m/s. If the wall exerts an average force of 300N acting in the x-direction for 0.006s then what is the final velocity of the ball after leaving the wall?

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.
