Problem 63P

Problem 63P

A puck on a horizontal, frictionless surface is attached to a string that passes through a hole in the surface, as shown in. As the puck rotates about the hole, the string is pulled downward, bringing the puck closer to the hole. During this process, do the puck's (a) linear speed, (b) angular speed, and (c) angular momentum increase, decrease, or stay the same?

Solution 63P

Part (a)

Step 1 of 3:

A puck rotates about the hole on a horizontal table. It is attached to a string and the string is pulled down. The puck is brought closer to the hole. We are going to find the linear speed of the puck.

The angular momentum of the puck is constant as the string exerts no torque on it. Therefore

L = mvr = constant

v

The radius of the circular path decreases as the puck approaches the hole and the linear speed increases.

Part (b)
