Answer:
F = 2985.125 N
Step-by-step explanation:
Given that,
The radius of curvature of the roller coaster, r = 8 m
Speed of Micheal, v = 17 m/s
Mass of body, m = 65 kg We need to find the net force acting on Micheal. Net force act the bottom of the circle is given by :
![F=(mv^2)/(r)+mg\\\\F=m((v^2)/(r)+g)\\\\=65((17^2)/(8)+9.8)\\\\=2985.125\ N](https://img.qammunity.org/2022/formulas/physics/college/r3ffj6fq94f7nfdgxqmbuj6aj8np6uujov.png)
So, the net force is 2985.125 N.
