A 2.0 g bead slides along a frictionless wire, as shown in the figure. At point A, the bead is moving to the right but with negligible speed.
 
  (a) What is the potential energy of the bead at point A?
  (b) What is the kinetic energy of the bead at point B?
  (c) What is the speed of the bead at point B?
  (d) What is the speed of the bead at point C?
 
  What will be an ideal response?

Question 2

requires 6.0 J of work is needed to push a 2.0-kg object from point A to point B of the frictionless ramp as shown in the figure. What is the length s of the ramp from A to B?
 
  What will be an ideal response?
