Problem: Rotating puck weight A mass m, slides in a circular path with speed v on a horizontal frictionless table it is held at a radius r by a string threaded through a frictionless hole at the center of the table. At the other end of the string hangs a second mass m2 What is the tension in the string T? What is the speed of the sliding mass v Physics 121: Lecture 11, Pg 5Physics 121: Lecture 11, Pg 5 Problem: Rotating puck & weight. A mass m1 slides in a circular path with speed v on a horizontal frictionless table. It is held at a radius R by a string threaded through a frictionless hole at the center of the table. At the other end of the string hangs a second mass m2 . What is the tension in the string T ? What is the speed of the sliding mass v ? m1 m2 v R
