Question

Please someone help me.

A car starts to move from rest after 5 seconds its velocity becomes 15m/s, find the acceleration of the car.​

Answer 1

3m/s

Simple

Step-by-step explanation:

Solution,

U=0

Velocity=15m/s

Time=5 sec

Now,

Acceleration=V-U÷T

=15m/s-0÷5

=15m/s÷5

=3m/s

Hence, the acceleratiob of the car is 3m/s.

Answer 2

acceleration of the car is 3 m\s^2

Step-by-step explanation:

from rest means the initial velocity (vi) is zero

time = 5s

final velocity (vf) = 15m\s

a = vf - vi \ t

a = (15-0) \ 5

a= 3 m\s^2

which means that the car is speeding up 3 meters every second
