Question 19

Two toy cars A and B of masses 200 g and 500 g respectively are moving with the same speed. Which of the two has greater kinetic energy?

Answer

The toy car B has greater kinetic energy than toy car A.

Reason — The two toy cars A and B are moving with the same speed. As the toy car B has greater mass (500 g) than toy car A (200 g) hence its kinetic energy is also greater.
