Question:
A hairpin turn on a concrete racetrack has a radius of 117 ft.
(a) Since the frictional force between the road and the tires acts as the centripetal force, find the vehicle’s maximum possible speed around the turn. (The coefficient of starting friction between rubber and concrete is 2.00.)
(b) What would be the maximum velocity around the next turn if it has double the radius of the first turn?
(c) Explain how the radius of a turn influences the centripetal force and the maximum velocity for a vehicle.

Centripetal force is the component of force acting on an object in curvilinear motion which is directed towards the axis of rotation or center of curvature. For this experiment : Take a rectangular or square shaped thin sheet. Take a screwdriver or something to make four holes in each corner of the rectangular shape sheet. Now take four equal sized ropes and connect to each hole. Now tie the other ends of the rope by leveling the board to ground like this and tape it.. We will test the Centripetal force phenomena with different objects like Iphone 6, 12 and 11.
