a. Write a realistic problem for which this is the correct equation.

b. Finish the solution of the problem, including a pictorial representation.

a) The realistic problem will be :

"A force of 1400 N is experienced by a 100g ball that is moving towards right with speed 40 m/s and rebounds with 30 m/s. Find the time that the ball takes in contact with the ball"

b) Solution for the equation is

We need to find out a realistic problem for which this is the correct equation and have to find out the solution including pictorial representation.

In this equation, momentum of the same mass changes due to an impulse.

Therefore, The realistic problem will be :

"A force of 1400 N is experienced by a 100g ball that is moving towards right with speed 40 m/s and rebounds with 30 m/s. Find the time that the ball takes in contact with the ball "
