Homework Statement
A single conservative force acting on a particle varies as Fvec = (-Ax + Bx4)i N, where A and B are constants and x is in meters. Accurately round coefficients to three significant figures.
(a) Calculate the potential energy function U(x) associated with this force, taking U = 0 at x = 0. (Use A, B, and x as appropriate.)
(b) Find the change in potential energy and change in kinetic energy as the particle moves from x = 1.80 m to x = 3.40 m. (Use A, B, and x as appropriate.)
Homework Equations
w = f x d
The Attempt at a Solution
ive only attempted part a since i think i will need it to go on to part b.
w = f x d
f = (-Ax + Bx4)
d = x
PE = (-Ax + Bx^4)x = -Ax^2 + Bx^5
