Question

A 150 g ball is thrown towards a wall with a speed of 6.5 m/s. If bounces off the wall with a speed of 3.5 m/s, determine the impulse provided by the wall.

Answer 1

Answer:1500Ns

Step-by-step explanation:

Mass(m)=150g

Initial velocity(u)=-6.5m/s

Final velocity(v)=3.5m/s

Impulse=change in momentum

Change in momentum=m(v-u)

Change in momentum=150(3.5-(-6.5))

Change in momentum=150(3.5+6.5)

Change in momentum=150(10)

Change in momentum=1500Ns
