Question

A car is stopped at a red light. When the light turns green, the car accelerates until it reaches a final velocity of 45 m/s. It takes the car 12 s to reach this speed. How far does the car travel during this time.

Answer 1

270 m

Step-by-step explanation:

We can find the distance travelled by the car by using the following suvat equation:

`s=((u+v)/(2))t`

where

s is the distance travelled

u is the initial velocity

v is the final velocity

t is the time

For the car in this problem,

u = 0

v = 45 m/s

t = 12 s

Substituting into the equation, we find:

`s=((0+45)/(2))(12)=270 m`
