A father is concerned that his teenage son is watching too much television each day, since his son watches an average of 2 hours per day. His son says that his TV habits are no different than those of his friends. Since this father has taken a stats class, he knows that he can actually test to see whether or not his son is watching more TV than his peers. The father collects a random sample of television watching times...

A bicyclist who has a mass (including their bike) of 85 kg is racing around a track. The radius of curvature of the track is 20 m. The bicyclist’s linear velocity is 17 m/s. Given the bicyclist is at a constant speed, staying level (not going up or down, therefore no vertical acceleration), what angle does the track need to be banked so that NO frictional force is required to keep their circular path?
