1. (5p) A person drops a pebble of mass mā from a height h, and it hits the floor with kinetic energy KE. The person
drops another pebble of mass m2 from a height of 4h (four times the height), and it hits the floor with the same
kinetic energy KE. How do the masses of the pebbles compare? (e.g. determine the ratio between mā and m2.)
A numerical value is required for credit. (neglect air friction). SHOW YOUR WORK.
