Question

A car accelerates from rest to 12 m/s in 4 seconds. What is its acceleration?

Answer 1

Answer:

The answer is 3.0 m/s²

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

$a = \frac{v}{t}$

where

a is the acceleration

v is the velocity

t is the time

From the question

v = 12 m/s

t = 4 s

We have

$a = \frac{12}{4}$

We have the final answer as

3.0 m/s²

Hope this helps you
