A force on an object is given by F(x) = ( -4.00 N/m)x + ( 2.00 N/m3)x3. What is the change in potential energy in moving from  x= 1.00  to  x=2.00 m?

A hockey puck having a mass of 0.30 kg slides on the frictionless, horizontal surface of an ice rink. Two hockey sticks strike thepuck simultaneously, exerting the forces on the puck shown in Figure. The force F1 has a magnitude of 5.0 N, and the force S F2 has a magnitude of 8.0 N. HOCKY.png Magnitude of the pucks x- component of total acceleration is :
