Question

A man weighing 60 kg is walking with a uniform velocity of 4 m $s^{-1}$. Calculate the momentum of a man.

• A. 120 m $s^{-1}$
• B. 240 m $s^{-1}$
• C. 360 m $s^{-1}$
• D. 480 m $s^{-1}$

Answer 1

The correct option is B 240 m $s^{-1}$

Given,

$m=60kgv=4m/s$

Momentum = mass $\times$ velocity.

Momentum of man $p=m\times v=60\times 4=240kgm/s$
