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

Question 2

As a particle moves along the x axis it is acted upon by a single conservative force given by Fx = (20 - 4.0x) N where x is in m. The potential energy associated with this force has the value +30 J at the origin (x = 0). What is the value of the potential energy at x = 4.0 m?
 a. -48 J
  b. +78 J
  c. -18 J
  d. +48 J
  e. +80 J
