Question

If an object moves in uniform circular motion in a circle of radius R=2.00 meters, and the object takes 5.00 seconds to

Answer 1

Answer:

The centripetal acceleration of the object is $315.5\ m/s^2$.  

Explanation:

We have,

Radius of a circular path is 2 m

It takes 5 seconds to complete 10 revolutions. It means its angular velocity is :

$\omega=\dfrac{\Delta \theta}{\Delta t}\\\\\omega=\dfrac{2\pi \times 10}{5}\\\\\omega=12.56\ rad/s$

The centripetal acceleration of the object is given by :

$a=\omega^2 r\\\\a=(12.56)^2 \times 2\\\\a=315.5\ m/s^2$

So, the centripetal acceleration of the object is $315.5\ m/s^2$.
