[mwit1967]

Consider the motion of a 1.00-kg particle that moves with potential energy given by U(x) = -(2.0 Jm)/x + (4.0 Jm2)/x2. Suppose the particle is moving with a speed of 3.00 m/s when it is located at x = 1.00 m.
 
  What is the speed of the object when it is located at x = 5.00 m? A)
 
  2.13 m/s
  B)
 
  3.00 m/s
  C)
 
  4.68 m/s
  D)
 
  3.67 m/s
  E)
 
  This question cannot be answered. You need to know the direction of the velocity, not just the speed, when the particle is located at x = 1.00 m.
