4. A cyclist is pedaling around a circular level track of radius 45m. The coefficient of static friction between the tires and track is 0.48 and the coefficient of kinetic friction is 0.45. (a) What is the maximum speed of the cyclist without the tires slipping? (b) At this speed, the cyclist suddenly brakes, locking the wheels, and slides to a halt. How far do they slide and in what direction?

A Wall of Death is a carnival show featuring a motorcyclist rides along the vertical wall of the cylinder and performs various stunts while doing so. Given that the radius of the cylinder is 7 m and the static coefficient of friction is 0.8, what is the minimum speed in m/s2 that the motorcyclist must do to prevent the motorcycle to slip from the wall?
A 0.50-kg object moves on a horizontal frictionless circular track with a radius of 2.5 m. An external force of 3.0 N, always tangent to the track, causes the object to speed up as it goes around. If it starts from rest, then at the end of one revolution the radial component of the force of the track on it is:
