Question

A particle moving at 30 m/s West has a momentum of 1598 kg.m/s West, calculate the mass of the particle.

Answer 1

By the definition of the momentum we have:

$p = mv,$

here, $p$ is the momentum of the particle, $m$ is the mass of the particle and $v$ is the velocity of the particle.

Then, from this formula, we can find the mass of the particle:

$m=\frac {p}{v}= \frac {1598}{30}= 15.3kg$

m=53.3kg
