# A force in the negative direction of an x axis is applied for 32 ms to a 0.75 kg ball initially moving at 15 m/s in the positive directionof the axis. The force varies in magnitude, and the impulse has magnitude 49.6 N s. (a) What is the ball's velocity (including sign fordirection) just after the force is applied? (b) What is the average magnitude of the force on the ball?(a) NumberUnits(b) NumberUnits

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,

...
