Answer:

t = 1.33 seconds

Step-by-step explanation:

Given that,

The mass of the ball, m = 5 kg

Initial speed, u = 8 m/s

Final speed, v = 12 m/s

Force, F = 15 N

We need to find the time for long the force is applied. Let the time be t. The force is given by :


F=(m(v-u))/(t)\\\\t=(m(v-u))/(F)\\\\t=(5* (12-8))/(15)\\\\=1.33\ s

So, the force is applied for 1.33 seconds.
