Avelodrome is built for use in the olympics. the radius of curvature of the surface is 20.0 m. at what angle should the surface be banked for cyclists moving at 15.5 m/s? (choose an angle so that no frictional force is needed to keep the cyclists in their circular path. large banking angles are used in velodromes.)

Explanation:

The radius of curvature of the velodrome, r = 20 m

Speed of cyclists, v = 15.5 m/s

Let is the angle at which the surface should be banked. The horizontal and vertical forces acting on the cyclists are as follows :

From  the above two equations,

So, the angle at which the surface is banked is 50.79 degrees. Hence, this is the required solution.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

c) power lifting, will be your answer.
