Question

A man driving his sports car with 5,250 kg at auniform speed of 25 km/a in north east. What is the momentum of his sports car?

Answer 1

Explanations & Calculations

• It is the product $\small m.v$ along the moving direction.
• Therefore,

$\qquad\qquad \begin{aligned} \small P&=\small mv\\ &=\small 5250\,kg\times (\frac{25\times1000m}{3600\,s})\\ &=\small 36458.3\,kgms^{-1}[north-east] \end{aligned}$
