Question

The winter sport of curling involves sliding a large granite stone on ice with the objective of placing it closest to the center of the ring. The curler causes the path of the stone to curve by giving it an initial circular rotation. Sweepers use brooms to sweep the path in front of the stone. How does the motion of the sweepers relate to the conservation of angular momentum?

The sweepers minimize friction between the stone and ice which helps maintain the angular momentum.

The sweepers motion creates circular air motion which adds to the angular momentum.

The sweepers motion adds torque to the stone's angular momentum.

The sweepers create circular patterns in the ice to increase the angular momentum.

Answer 1

The sweepers motion adds torque to the stone's angular momentum.

Step-by-step explanation:

This is due to angular momentum law.
