Homework Statement
A copper block rests 33.8 cm from the center of a turntable. The coefficient of static friction between the block and turntable is 0.52. The table starts from rest and accelerates with an angular acceleration of 0.226 rad/s².
Acceleration of gravity = 9.8 m/s².
After what interval, in seconds, will the block start to slip on the turntable?
Homework Equations
Tangential acceleration = angular acceleration * radius, so At = 0.226 * 0.338 = 0.0764 m/s².
The Attempt at a Solution
I've got the turntable drawn out with a radius of 0.338 m, a block on the edge with unknown mass and a tangential acceleration of 0.0764 m/s², and µ = 0.52.
I'm a little hazy on how to progress; does the lack of mass information pose a problem?
