Question

How much energy is required to stop a car of mass 3 quintal with speed of 144m/s(-1) ?​

Answer 1

Answer:-

• Mass=3Quintal=300kg
• Velocity=144m/s
• Momentum=?

We know that

$\boxed{\sf Momentum=Mass\times Velocity}$

$\\ \sf\longmapsto Momentum=300\times 144$

$\\ \sf\longmapsto Momentum=43200kgm/s$
