Question

a car starts from rest and moves with a speed of 20m/s . after 8s the speed of the car becomes 60m/s. what is the change in velocity​

Answer 1

Answer:

The acceleration of the car is solved by using the definition of acceleration. Acceleration is the rate of change in the body’s velocity per unit time. In formula form a = final velocity - initial velocity / time. In symbols it is a = (vf - vi) / t

a = (20 m/s - 0 m/s) / 8 s

a = 5/2 m/s^2

a = 2.5 m/s^2

Answer 2

Explanation:

2.5 m/s² is the answer hope it is helpful
