A47 kg person in a rollercoaster moving through the bottom of a curved track of radius 47.7 m feels a normal force of 895 n. what is the net centripedal force acting on the person

434.4 N

Explanation:

There are two forces acting on the person when it is at the bottom of the trajectory:

- Its weight W = mg (m= mass, g= acceleration of gravity), acting downward

- The normal reaction N, acting upward

So the net centripetal force Fc is given by

Substituting:

N = 895 N

m = 47 kg

We find:

what are the options.

explanation:

your answer is c! hope this : )
