Question 65
Two balls of steel having mass of 5 kg and 10 kg each possess equal kinetic energy.
Which ball is moving faster, if at all?
Solution
Formula of kinetic energy = $$\frac{1}{2}mv^2$$
Since both the balls have same kinetic energy, ball with lower mass would have higher velocity.
So , the answer would be Option b)The 5 kg ball is moving faster.
