I have attempted each problem, but am getting lost on just what to do to solve. If i could be pointed in the right direction on how i should go about each problem that would be nice. Attached are my attempts at problems 1-3.

See attatchments for attempts at first 3
attempt at problem 4
M = .150kg D = .65 m
F(x) = 15000 + 10000x -25000X^2
A) work done = ∫F(x)dx = ∫15000 + 10000x -25000X^2 dx
= 15000x + 5000x^2 - ((25000x^3)/3) bounded from 0 to 65 = -9572 JoulesI only need help with part A for problem 4. I feel like i had to have done something wrong or i approuched the problem wrong because a negative answer doesn't seem to make sense.
