A motorcycle has a constant speed of 27.8 m/s as it passes over the top of a hill whose radius of curvature is 192 m. The mass of the motorcycle and driver is 323 kg. Find the magnitude of (a) the centripetal force and (b) the normal force that acts on the cycle.

Explanation:

Given that,

Speed of a motorcycle, v = 27.8 m/s

Radius of curvature of the path, r = 192 m

The mass of the motorcycle and driver is 323 kg, m = 323 kg

(a) The centripetal force acting on the motorcycle is given by :

The centripetal force is .

(b) The normal force acting on the cycle is given by :

Hence, this is the required solution.

answer: i don't know the answer good luck

explanation:

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
