Consider the Motion of a 1

question 51

Multiple Choice

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.
