# Calculating the Acceleration of a Car

## Understanding Car Acceleration

Acceleration is an important concept in physics that measures the rate of change in velocity of an object. When a car accelerates uniformly, it means that the velocity of the car increases by the same amount in equal time intervals.

## The Formula for Acceleration

The formula to calculate acceleration is:

**a = (v - u) / t**

Where:

**a**= acceleration**v**= final velocity**u**= initial velocity (in this case, the car starts from rest)**t**= time taken to reach the final velocity

## Given Data

A car accelerates uniformly from rest to 25 m/s over a distance of 30 meters. We need to find the acceleration of the car.

## Calculating Acceleration

Given that the car starts from rest, the initial velocity **u** is 0 m/s. The final velocity **v** is 25 m/s, and the distance **s** is 30 meters.

**Answer:**

a = (v^{2} - u^{2}) / 2s

a = (25^{2} - 0) / 2*30

a = 625 / 60

a = 25/24 m/s^{2}

**Explanation:**

Based on the calculations, the acceleration of the car is 25/24 m/s^{2}.

What is the acceleration of the car?

a = 25/24 m/s^2

Explanation: I'm going to assume you mean the final velocity is 25m/s.

v^2 = u^2 + 2as

625 = 0 + 2a300

a = 25/24 m/s^2 or 1.0416 m
