44. A single conservative force acting on a particle variesas F=(-Ax +Bx^2)i N, where A and B are constants and x is in meters(a)   Calculate the potential energy function U(x)associated with this force, taking U=0 at x=0. (b) Find the changein potential energy and the change in kinetic energy of the systemas the particle moves from x=2.00m to x=3.00m.
