Consider the motion of a 1.00-kg particle that moves with potential energy given by U(x) = -(2.0 J?m)/x + (4.0 J?m2)/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.
