5. (2 pts) Assume that you are going to race two solid spheres (with radius 3 cm and 5 cm respectively) by releasing them from the top of an inclined plane and do not slip. Which sphere reaches the bottom of the inclined plane first? a) the smaller sphere

  1. the bigger sphere
  2. they both reach the bottom at the same time
  3. it depends on the height of the inclined plane

6. (3 pts) If the two solid spheres (with radius 3 cm and 5 cm respectively) have masses 5 g and 10 g respectively, which sphere has a higher moment of inertia? a) the smaller sphere

  1. the bigger sphere
  2. they both as the same moment of inertia
  3. it depends on the density of each sphere

Two uniform solid spheres are joined by a light rigid rod to form a dumbbell. The spheres are identical, and each has mass M/2. One end of a spring is attached to the center of the rod, the spring is stretched perpendicular to the rod, and the other end of the spring is attached to a wall. The dumbbell rests on a horizontal surface. Friction between the surface and the spheres prevents slipping. The system is released from rest. a)...
