Step 1

Given:

Direction of force is in negative x direction.

Implementation of force for time (t) = 32 ms.

Mass of the ball (m) = 0.75 kg.

Initial velocity of ball (u) = 15 m/s.  (+x direction)

Magnitude of impulse (P) = 49.6 Ns.

Step 2

Part a)

The impulse is given as, Step 3

Part b)

The acceleration of ball during the application of force, ...
