Question

what is force exerted by the table on the ball to bring it to rest​

Answer 1

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.

Answer 2

Answer:

In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity
