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
complete ten revolutions, calculate the centripetal acceleration.
• ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are
measurements.
a=
m/s2
39.4 m/s2
50.2 m/s2
100. m/s2
158 m/s2

The centripetal acceleration of the object is .  

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 :

The centripetal acceleration of the object is given by :

So, the centripetal acceleration of the object is .

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /
