Question

A body og mass 1000kg is at rest. Calculate the force required
to impart a velocity of 20 ms^-1 in 10
sec.​

Answer 1

ATQ; velocity = 20m/s

         time = 10sec.

Therefore, acc. = 20/10 = 2m/s^2

Mass = 1000kg = 1000000m

We know that, F=ma

So, Force = 1000000m / (2)m/s ^2  = 500000N
