Answer:
Mass of the body, m=20 g=0.02 kg
From the given graph, we note that
Initial velocity, u=20 m/s=20 m/s
Final velocity, v=0 m/s
Time taken, t=10−0=10s
The force exerted on the ball is,
F=m x a
F=m x (v−u)/t
F=−0.04 N
The negative sign shows that the friction force exerted by the table is opposite to the direction of motion of the ball.
