I understand the concept of free body diagrams, but there are so many formulas that I really need help choosing which ones to use for this specific problem.
Homework Statement
A block of ice slides down a frictionless ramp at theta = 60 degrees while an ice worker pulls on the block (via a rope) with a constant force of 50.0 N. The block slides a distance d = 0.8m along the ramp and its kinetic energy increases by 128 J.
(a) Calculate the work...
