What will be the momentum of a body of mass $0.5kg$ moving with a speed of $10\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$.

Step 1. Given data:

mass $\left(m\right)$= $0.5kg$

speed $\left(v\right)$= $10\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$

Step 2. Calculations:

Momentum:

1. It is a property of a moving body that the body acquires due to its mass and motion.
2. It is equal to the product of the body's mass and speed.
3. Mathematically: Momentum $\left(p\right)$=mass$\left(m\right)\times$speed$\left(v\right)$

So Momentum = mass x speed

$p=\left(0.5\times 10\right)=5kg.\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$.

Hence momentum of the body will be $5kg.\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$
