Two marbles of masses m and 2m are dropped from a height h. Compare their kinetic energies when they reach the ground.
Added by Santiago S.
Step 1
Both marbles are dropped from the same height h, so they have the same initial potential energy. Show more…

Two marbles of masses $m$ and $2 \mathrm{m}$ are dropped from a height $h$. Compare their kinetic energies when they reach the ground.
A person drops a pebble of mass m1 from a height h, and it hits the floor with kinetic energy K. The person drops another pebble of mass m2 from a height of 2h, and it hits the floor with the same kinetic energy K. How do the masses of the pebbles compare?
