Question

What is the what is the acceleration of a car starts from rest and acquired a velocity of 40m/s in 8 s

Answer 1

Answer:

5 m/s^2

Explanation:

We know,

Acceleration , a = (Final velocity - Initial velocity)÷ Time

Here,

Final velocity , v = 40m/s

Initial velocity , u = 0 m/s ( as starting from rest , the velocity will be 0 )

Time , t = 8 s

So,

a= ( v - u ) ÷ t

=. ( 40 - 0 ) ÷ 8

= 5 m/s^2

Therefore , the acceleration of the car is 5 m/s^2.
