Question

A force of 10 N acts on a body of mass 2 kg for 3s, initially at rest. Calculate i) The velocity acquired by the body

Answer 1

Answer:

15m/second

Explanation:

Hope it helps.

Answer 2

Explanation:

Solution,

Force = 10 N

Mass = 2 kg

Time (T) = 3s

Initial velocity (v) = 0 m/s

We have,

F = ma

Or, 10 = 2 a

Or, 10 /2 = a

Or, 5 =a

Hence acceleration = 5 m/s^2

Now

a = v - u / t

Or, 5 = v - o / 3

Or, 15 =v

Hence final velocity (v) = 15 m/s
