1. The problem statement, all variables and given/known data There is a block on a turntable. It is attached to the center of the table by a string with the length .4m. Also the static friction constant between the table and the block is 0.8 . If the maximum tension the string can support is 300n how fast can the table spin without the string snapping? 2. Relevant equations mass (velocity)^2 / radius = Centripetal Force mass x 9.8 [gravity] x U [friction constant] = Force of Friction 3. The attempt at a solution mv^2/.4 = 300 + .8mg V = sqr(120/m +3.136) Where do I go from here? Can I find a quantitative value for velocity if the mass of the block is not given? Thanks! I would appreciate it if I can get an answer tonight. My impression is that this is due tomorrow.
