Question

A body of mass 2 kg is at rest. what should be the magnitude of force which will make the body move with a speed of 30 m/s at the end of 1s?

Answer 1

Hey mate!

Here's your answer!!

m = 2 kg

u = 0 m/s

v = 30 m/s

t = 1 s

F = ma

$f = m( \frac{v - u}{t} ) = 5( \frac{30 - 1}{1} ) = 150n$
Thus, the magnitude of force which will make the body move with a speed of 30km/s at the end of 1s is 150N.

$hope \: it \: helps \: you.$
