1. The problem statement, all variables and given/known data Find the work W done on the block by the force of magnitude F = 85.0N as the block moves from xi = -3.00cm to xf = 5.00cm. 2. Relevant equations W = F*S*cos(theta) 3. The attempt at a solution W = (85.0N)(-3cm-5cm)*1 W = -260J Am I missing something?
