Question
An object of mass m =
3 kg moves in the x direction with the potential
energy U (x) shown. There are no other forces acting. On the axes provided below the graph
of U (x), sketch the force F(x) that the mass experiences. If the object is released from rest
at x = -2 where U = 16J, what is its velocity at x =
O where U = -8J?
