**A Car Starts from Rest and Moves with a Uniform Acceleration** ===========================================================

Introduction

In this article, we will explore the concept of uniform acceleration and its application in real-world scenarios. We will use a car as an example to calculate the distance covered at the end of a motion with a uniform acceleration.

Understanding Uniform Acceleration

Uniform acceleration is a type of acceleration that occurs when an object moves with a constant rate of change of velocity. In other words, the acceleration of the object remains the same over a period of time. This type of acceleration is often seen in objects that are moving under the influence of gravity or in situations where the force applied is constant.

Calculating Distance Covered

To calculate the distance covered by a car moving with a uniform acceleration, we can use the following formula:

Distance = Initial Velocity × Time + (1/2) × Acceleration × Time^2

In this formula, the initial velocity is the velocity of the car at the start of the motion, the time is the duration of the motion, and the acceleration is the rate of change of velocity.

Given Values

In this problem, we are given the following values:

Initial Velocity (v0) = 0 m/s (since the car starts from rest)
Acceleration (a) = 3 m/s^2
Time (t) = 20 s

Calculating Distance

Using the formula above, we can calculate the distance covered by the car as follows:

Distance = 0 × 20 + (1/2) × 3 × 20^2 Distance = 0 + (1/2) × 3 × 400 Distance = 0 + 600 Distance = 600 m

Therefore, the distance covered by the car at the end of the motion is 600 meters.

Conclusion

In this article, we have seen how to calculate the distance covered by a car moving with a uniform acceleration. We have used a simple formula to calculate the distance and have applied it to a real-world scenario. This type of calculation is essential in understanding the motion of objects and is widely used in various fields such as physics, engineering, and transportation.
