1. The problem statement, all variables and given/known data 1. An air puck of mass .25 kg is tied to a string and allowed to revolve in a circle of radius 1.0 m on a frictionless horizontal table. The other end of 2. the string passes through a hole in the center of the table, and a mass of 1.0 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves. 3. 4. a. What is the tension in the string? Answer: 9.8 5. b. What is the speed of the puck? Answer:: 6.26 6. c. If the table is not frictionless, but instead is made of a material with a coefficient of friction u=0.45, how do your answers for a) and b) change? (answer: ?) 2. Relevant equations v=(2*pi*R)/T a=(v^2)/R 3. The attempt at a solution I'm not sure. How would the situation even apply? (I only need help with part c).
