Question

The velocity-time graph of a ball moving on the surface of floor is shown in the figure. Calculate the force acting on the ball, if mass of the ball is 100g.

Answer 1

Answer:

 0.5N

Explanation:

a=v-u/t

 =(20-0)/4

 =5m/s^2

F=ma

 =0.1kg * 5

 0.5N

Answer 2

Answer:

o.5N (N=Newton)

Explanation:

a=v-u/t

a=(20-0)/4

a=5m/s^2

F=ma

=0.1kg×5

0.5N
