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?

Banked Racetrack Without Friction A puck is sliding around a circular track that is banked at an angle with respect to the horizontal such that no friction between the puck and the track is required to keep the puck from slipping up or down the track. If the puck is moving at a speed 30.9 m/s and the radius of the track is 405 m, determine θ. Suhmit Answer

You ride a bicycle around on a circular track while accelerating. The circle has a radius of 22 m and your cell phone tells you that your total acceleration is 12 m/s2 making an angle 44⁰ from the forward direction of your bike (t̂) into the circle. Find: (a) your radial acceleration, (b) your current speed, and (c) the rate of change of your speed.

Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...
