Question
A 20 kg object is acted on by a conservative force given by
F=3.0x - 5.0x2, with F in newtons and x in meters. Take the
potential energy associated with the force to be zero when the
object is at x = 0. (a) What is the potential energy of the system
associated with the force when the object is at x 2.0 m? (b) If
the object has a velocity of 4.0 m/s in the negative direction of the
x axis when it is at x = 5.0 m, what is its speed when it passes
through the origin? (c) What are the answers to (a) and (b) if the
potential energy of the system is taken to be 8.0 J when the object
is at x = 0?
