# A small puck of mass \(0.50\text{ kg}\) is attached to the end of a string and slides on a frictionless horizontal tabletop in a circular path of radius \(1.5\text{ m}\). The puck moves at a constant speed of \(6.0\text{ m/s}\). What is the magnitude of the linear momentum of the puck at any point in its motion?

![A top-down view of a horizontal circular trajectory centered on an origin dot. A straight radial line segment connects the center dot to a solid filled circle representing the puck. A dashed circle with radius labeled r outlines the circular path. A single tangential straight arrow points perpendicularly from the puck along the counterclockwise circular path, labeled v. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787460167-y2ZBDv.jpg)
