"A cyclist competes in a one-lap race around a flat, circular course of radius r . Starting from rest and speeding up at a constant rate throughout the race, the cyclist covers the entire course in a time t. The mass of the bicycle (including the rider) is m. What is the magnitude of the net force acting on the bicycle as it crosses the finish line?(adsbygoogle = window.adsbygoogle || []).push({});

Find F(net), the magnitude of the net force acting on the cyclist at the finish line.

Express the net force in terms of r, t,m , and pi."

First I tried to break it down into components.

F(net) = sqrt (net tangential force^2 + net radial force^2)

net tangential force = (m4pi*r)/t^2

I know that I will need to use Newton's 2nd law to find the tangential force. But I can't figure out how to do this.

As for the net radial force I know that I somehow need to use tangential force but since I'm stuck there that's as far as I got.

Thanks.
