You drop two balls from a tower, one of mass m and the other of mass 0.2m.
Just before they hit the ground, which ball, if either, has the larger kinetic energy?
The ball of mass m would have the larger kinetic energy I believe, but I’m not positive. Any help would be greatly appreciated.

Same acceleration, same distance to fall -> same velocity just before impact
Ek = 1/2mv^2
The only difference is in m, so the Ek will differ by the ratio of the masses.
The larger mass ball will have more Ek.

FORMULA FOR KINETIC ENERGY IS
K.E=1/2 M (SQUARE OF VELOCITY)
since the bodies are left at same time so they have same velocities before reaching ground……
Simply kinetic energy is directly proportional to the mass of body….SO THE BODY WITH GREATER MASS HAVE GREATER KINETIC ENERGY….
