Here's what I have so far:

35 x 9.8 = 343 N

And I don't know how to solve this problem. Please provide a step by step solution! I know you use the formula:

W = (F (dot) d)(cosx)

Textbook Answer: 2114 J

I am assuming the force does not change direction when one gets tothe top, the problem is unclear to me on that point.
