Two boxes are set up in a system as shown in the attached picture.
Box 1 - mass = 5 kg
Box 2 - mass = 2 kg
h = 5m
The system is released, and box 2 hits the ground. With a frictionless system, find the total KE before box 2 hits the ground.
I am fairly sure I have to use the conservation of energy, which in this case would be:
The Attempt at a Solution
I dont quite understand how to go about this problem with the two box system. I can figure out the boxes force and acceleration, but not what I need.
