A l.18-kg object is acted on by a net conservative force given exactly by F; = Ax + Bx 2 where A = - 3.00 N/m and B = - 5.00 N/m 2 (a) Find the potential energy of the system at x = 2.26 m. Assume that U(0) = 0. (b) The object has a speed of 4.13 m/s in the negative x direction when it is at x =4.91 m. Find its speed as it passes x = 1.77 m.
