A painter on a wooden plank drops a 1.50-kg can of paint from a height of 6 m. Find the following: (A) KE when the height is 4 m above the ground. (B) speed of the can 4 m above the ground. (C) speed of the can 1 m above the ground.

falls 2 meters
Ke = m g (2) = 1.5 * 9.8 * 2

(1/2) m v^2 = 1.5 * 9.8 * 2
or
v^2 = 9.8 * 4

falls 5 m from 6 to 1 meter
(1/2) m v^2 = m g (5)
v^2 = 9.8 * 10

in general falling distance h
v= sqrt (2 g h)
