Answer:
Force, F = 135 N
Step-by-step explanation:
Given that,
Mass of the bicyclist, m = 90 kg
Centripetal acceleration of the bicyclist,
![a=1.5\ m/s^2](https://img.qammunity.org/2020/formulas/physics/middle-school/h3lz52egbepd9d0w6xtxxtyjfc9h87z19k.png)
To find,
The centripetal force acting on the bicyclist.
Solution,
When an object moves in a circular track, it will under the action of centripetal acceleration and the exerted force is called centripetal force. It can be calculated as :
![F=ma](https://img.qammunity.org/2020/formulas/physics/middle-school/hoqv0uuwk5hamoxytydy5e8slsjemaiqzz.png)
![F=90\ kg* 1.5\ m/s^2](https://img.qammunity.org/2020/formulas/physics/middle-school/glzl5we3xhprvfc2halltyrxlfq31u8s0b.png)
F = 135 N
So, the centripetal force acting on the bicyclist is 135 N.
