Textbook Problem

A solid disk and a hoop are simultaneously released from rest at the top of an incline and roll down without slipping. Which object reaches the bottom first? (a) The one that has the largest mass arrives first, (b) The one that has the largest radius arrives first, (c) The hoop arrives first, (d) The disk arrives first, (e) The hoop and the disk arrive at the same time.

To determine
The object which reaches the bottom first.

Explanation

The rotational energy is given by,

Erot=12Iω2

  • I is the moment of inertia.
  • ω is the angular velocity.

The moment of inertia of the disk is small. Therefore its rotational energy is less.

Conclusion:

The translational energy of the disk is large because its rotational energy is less. Therefore, option (d) is correct.

The one with the largest mass will have larger moment of inertia
