Question

A body having $5kg$ mass is traveling with a certain velocity and has $10kgm/s$ momentum. What will be its kinetic energy?

• A. 50 J
• B. 100 J
• C. 10 J
• D. 2 J

Answer 1

The correct option is C

10 J

$\text{Kinetic Energy}=\frac{\left({\text{Momemtum}}^2\right)}{2\times \text{Mass}}=\frac{100}{10}=10J$
