Consider the Motion of a 1

question 14

Multiple Choice

Consider the motion of a 1.00-kg particle that moves with potential energy given by
U(x) = (-2.00 J∙m) /x + (4.00 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
