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 = (v2 - u2) / 2s

a = (252 - 0) / 2*30

a = 625 / 60

a = 25/24 m/s2

Explanation:

Based on the calculations, the acceleration of the car is 25/24 m/s2.

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
