Consider the Motion of a 1

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 30.0 cm/s when it is located at x = 3.00 m. What is the position with the greatest value of x at which the particle comes to rest?

A) 6.73 m
B) 5.48 m
C) 8.69 m
D) 9.21 m
E) 7.29 m
