Question

A CRICKET BALL OF MASS OF 70 G MOVING WITH A VELOCITY

Answer 1

Explanation:

Mass of the ball=70 g

Initial Velocity(u)=0.5 m/s

Final velocity(v)=0

Change in momentum=m(v-u)=-70×0.5×10⁻³=0.035 kgm/s

Time taken=0.5 s

∴Force applied to stop the ball=change in momemtum/time taken=0.07 N
