In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely in contact with the track at the top of the loop.
 
  The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the magnitude of the force of the car on the track when the car is at point A. You can treat the car as a point mass.
 
  What will be an ideal response?

Question 2

A 5.00-kg object moves clockwise around a 50.0 cm radius circular path. At one location, the speed of the object is 4.00 m/s. When the object next returns to this same location, the speed is 3.00 m/s.
 
  (a) How much work was done by nonconservative (dissipative) forces as the object moved once around the circle?
  (b) If the magnitude of the above nonconservative (dissipative) forces acting on the object is constant, what is the value of this magnitude?
  What will be an ideal response?
