Answer:
![a=0.45\ m/s^2](https://img.qammunity.org/2021/formulas/physics/high-school/1fw8p2vb2alm8onz14xyk9s62ptilwgow8.png)
Step-by-step explanation:
Given that,
The radius of a bend, r = 20 m
Velocity of motorcyclist, v = 3 m/s
The combined mass of motorcyclist and the motorcycle is 50 kg
We need to find the motorcyclist’s centripetal acceleration. The formula used to find the centripetal acceleration is given by :
![a=(v^2)/(r)\\\\a=((3)^2)/(20)\\\\a=0.45\ m/s^2](https://img.qammunity.org/2021/formulas/physics/high-school/1z3za2wo8qwgt76v7s65xsgn2qatbot0g9.png)
So, the acceleration of the motorcyclist is
.
