Question

A body having an initial velocity of 36 kmph acquires a velocity of 20 ms-1 in 2s. Then find the acceleration of the body.​

Answer 1

Answer:

Acceleration of the body is 5 m/s²

Explanation:

Given:-

Initial Velocity, v = 36 kmph

= 10 m/s

Final velocity, v' = 20 m/s

Time period, t = 2 s

We know by formula that:-

Acceleration, a = v' - v / ∆t

Putting the given values in the formula, we get:

a = 20 - 10 / 2

a = 10/2

a = 5 m/s²

Hence, the acceleration of the body is 5 m/s².
