Question

A body of mass 25 kg has a momentum of 125 kg.m/s. Calculate the velocity of the body.

Answer 1

We know that:
Momentum = mass × velocity
= m × v
Here, mass, m = 25 kg
And, momentum = 125 kg.m/s
Putting these values in the above formula, we get:
125 kg.m/s = 25 × velocity
$$\begin{gathered} \Rightarrow \mathrm{Velocity}=\frac{125}{25} \\ \Rightarrow \mathrm{Velocity}=\frac{{\cancel{125}}^5}{\cancel{25}} \\ \Rightarrow \mathrm{Velocity}=5\mathrm{m}/\mathrm{s} \end{gathered}$$
