Answer 2

Answer:

Explanation:

Mass of the body, m = 20 g = 0.02 kg

From the given graph, we note that

Initial velocity, u = 20 cm/s = 0.20 m/s

Final velocity, v = 0 cm/s

Time taken, t = 10 - 0 = 10s

The force exerted on the ball is,

F= 0.0004N

The negative sign shows that the friction force exerted by the table is opposite to the direction of motion of the ball.
