# 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

See the step by step solution

## Step 1. Given 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.

## Step 2. Expressing the realistic problem of the given equation.

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 "

## Step 3. Finding the solution of the equation,

Pictorial representation :
