Question

A car is accelerated at a constant rate from 15 m/s to 25 m/s. It takes the car 6 s to reach its final speed. What is the car’s acceleration?

Answer 1

1.67 m/s²

Step-by-step explanation:

The car’s acceleration can be found by using the formula

`a = (v - u)/(t) \\`

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question we have

`a = (25 - 15)/(6) = (10)/(6) = (5)/(3) \\ = 1.666666...`

We have the final answer as

1.67 m/s²

Hope this helps you
