Question

The velocity -time graph of a ball of mass 160 g moving along the straight line on the ground is given below. Find how much force does the ground exerts on the ball to bring it to rest.

Answer 1

Answer:

Force=Mass×accleration

Force=0.16kg×change in velocity

Force=0.16Kg×(80-0)/8 m/s^2

Force=0.16kg×10m/s^2

Force=1.6Kgm/s^2 or 1.6 N

Answer 2

Answer:

Force =1.6kgms or 1.6 Newton
