Question

A particle moving at 30 ms-1 west has a momentum of 1598kg.ms-1 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:

$m = \dfrac{p}{v} = \dfrac{1598 kg \cdot ms^{-1}}{30 ms^{-1}} = 53.3 kg.$

Answer:

$m = 53.3 kg.$
