Calculate the efficiency of a system that uses a falling mass to move a box along the desk.
Given (helps to see picture):
Weight of (sliding) box = 164g
Weight of (falling) mass = 200g
Distance of board (platform) = 88cm
Time (avg) = 6s
(anything missing? I can get it, just point it out [its a lab])
Efficiency = (energy output/energy input) x 100%
The Attempt at a Solution
Ei = mad
E% = (Eo/Ei) x 100%
= (1.4J/1.7J) x 100%
Picture I made:

Any input to anything would be very helpful, and thanks for your time.
