Homework Help: Physics

Posted by Physicster on Saturday, March 13, 2010 at 9:43pm.

A 64 kg bicyclist rides his 7.7 kg bicycle with a speed of 13.5 m/s.

How much work must be done by the brakes to bring the bike and rider to a stop?

How far does the bicycle travel if it takes 4.5 s to come to rest?

What is the magnitude of the braking force?

I know the work in the first question is -6.43366 kJ but I have no idea how to find the distance and force.
