Question

A car starts at rest and accelerates at the rate 2m/s/s. How long does it take it to reach a velocity of

30m/s

Answer 1

The answer is 15 s

Step-by-step explanation:

The time taken for the car to reach

30 m/s can be found by using the formula

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

where

a is the acceleration

v is the velocity

t is the time

From the question we have

`t = (30)/(2) \\`

We have the final answer as

15 s
