question

A sphere, a cube, and a cylinder, all of equal mass, are released from rest from the top of a short incline. The surface of the incline is extremely slick, so much so that the objects do not rotate when released, but rather slide with negligible friction. Which reaches the base of the incline first?

choices

  1. the sphere
  2. the cube
  3. the cylinder
  4. All reach the base at the same time.
