Aroller coaster car travels through a loop in 3.1 s with a centripetal acceleration of 26 m/s^2. what is the radius of the roller coaster loop? a. 6.3 m b. 20 m c. 25 m

r = 6.32 meters

Explanation:

Given that,

The centripetal acceleration acting on the roller coaster,

Time taken by the car, t = 3.1 s

The centripetal acceleration act on an object when it moves in circular path. Its formula is given by :

v is the velocity of car,

On rearranging above equation,

r = 6.32 meters

So, the radius of the roller coaster loop is 6.3 meters. Hence, this is the required solution.
