You Pick up a 3.7 kg Can of Paint From the Ground and lift it to a height of 2.0 m.
(a) How much Work do you do on the can of paint?
(b) You Hold the can stationary for Half a Minute, waiting for a friend on a Ladder to Take it. How much work do you do during this Time?
(c) Your friend decides against the paint, so you lower it Back to the ground. How much work do you do on the can as you lower it?

a. w = f*D , f=m*a
f = 3.7 kg * 9.8m/s^2 = 36.26 N
w = 36.26 N * 2 m = 72.52 joules
