given that
mass of ball = 0.095 kg
initial velocity of ball towards the wall = 40 m/s
final velocity of the ball after it rebound = 30 m/s
now change in momentum is given as



So change in momentum will be 6.65 kg m/s

To solve this problem we will use the concepts related to the resulting Vector Force product of two components, that is,

If we take the Force of 50 N as the force in the X direction and the Force of 40 N in the Y direction we will have to:



Finally, since Newton's second law, acceleration can be determined as




Therefore the resultant magnitude of the acceleration of the object is
