## 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
