A sports car accelerates from rest for 5 seconds reaching a velocity of 23.0 m/s. a. What is the acceleration of the car?
Known:
t=
vi =
vf=
Unknown:
a =?
Equation:
vf=vi tat

Explanation:

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

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

Since the body is from rest u = 0

From the question we have

We have the final answer as

Hope this helps you
