# In Problems through you are given the equation(s) used to solve a problem. For each of these, you are to a. Write a realistic problem for which this is the correct equation(s). b. Draw a pictorial representation. c. Finish the solution of the problem

a. A toy car is used to move the block with mass is 2.0kg at rest, the velocity of the block on frictional surface of length is 4.0 m/s The coefficient of kinetic friction is 0.15

b. The pictorial presentation is as follow:

c. The tension in the string is

See the step by step solution

## Step 1: Content Introduction

Inertia is a fundamental feature of all matter, and mass is a quantitative measure of it. A force is a push or pull on an object caused by the interaction of the thing with another object.

## Step 2: Explanation (Part a)

A toy car is used to move the block with

mass is at rest,

the velocity of the block on frictional surface of length is .

The coefficient of kinetic friction is

## Step 3: Explanation (Part b)

The pictorial presentation is

## Step 4: Explanation (Part c)

Let T be the tension in string,

We are given,

Solve for T
