A 25.0 g, 2.25 cm wide marble rolls down a 65.0 cm high incline.

  1. What is its linear speed at the bottom? (5)
  2. What is the angular speed of the marble at the bottom? (2)
  3. A 1.00 mg speck of dust gets stuck to the edge of the sphere while it rolls down the incline. What is the dust’s angular momentum? (3)
  4. Bonus: Would a marble with a larger radius have a larger, smaller, or same linear velocity at the bottom?
