A 040-Kg Particle Moves Under the Influence of a Single Conservative

Multiple Choice

A 0.40-kg particle moves under the influence of a single conservative force. At point A where the particle has a speed of 10 m/s, the potential energy associated with the conservative force is +40 J. As the particle moves from A to B, the force does +25 J of work on the particle. What is the value of the potential energy at point B?

A) +65 J
B) +15 J
C) +35 J
D) +45 J
E) −40 J
