Homework Statement
Friction=0.8
r=50 m
T=?
Homework Equations
T=distance/speed
Perimeter=2*pi*r
Fc=(mv^2)/r
Ffriction=m*g*friction
The Attempt at a Solution
Perimeter
2*3.14*50=314
Fc=Ffriction
(mv^2)/r=m*g*friction
v=r*g*friction
= 50*9.82*0.8=391.8
T=314/391.8 = 0.8 s
Is this correct? Seems a bit wrong to me :S
