Answer:
Explanation:
Look at the equation for kinetic energy: KE = (1/2)m*v^2
Let n = mass, and k = velocity of one ball
while m = mass and v = velocity of another ball.
then, if the balls have the same kinetic energy
(1/2) n * k^2 = (1/2) m * v^2
==> n *k^2 = m * v^2
==> n/m = v^2/k^2
Which says the ratio of the masses is inversely proportional to the square of the velocities (so, to have the same kinetic energy, the heavier ball travels slower)
