Question

What is the acceleration of a car that starts from rest and achieves a speed of 45 m/s in 5 seconds?

Answer 1

Answer:

9m/s^2

Explanation:

solution,

Given. Initial velocity (u)=0m/s

Final velocity (v)=45m/s

Time taken(t)=5sec

Acceleration (a)=?

we know,

a=v-u/t

=45-0/5

=45/5

=9m/s^2

Therefore acceleration (a)= 9m/s^2
