Question

A car from rest It velocity becomes 20ms-1 in 8s find its acceleration​

Answer 1

Answer:

hope it helps

Explanation:

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

 Answer:

       a = 2.5ms⁻²

Explanation:

u = 0  ,  v = 20ms⁻¹ ,  t = 8s

v = u + at

a = v - u / t

a = 20ms⁻¹ - 0 / 8s

a = 20 / 8 ms⁻²

a = 2.5ms⁻²
