Aparticle travels in a circle of radius 82 cm and with a centripetal acceleration of 4.7 m/s2. how long does the particle take to complete one revolution?

Time, T = 2.62 seconds

Explanation:

Given that,

Radius of the circular path, r = 82 cm = 0.82 m

Centripetal acceleration of the particle,

To find,

Time taken to complete one revolution.

Solution,

The centripetal acceleration of the particle in circular path is given by :

is the angular velocity of the particle

Let T is the time taken by the particle take to complete one revolution. The relation between the angular velocity and the time is given by :

T = 2.62 seconds

So, the time taken to complete one revolution is 2.62 seconds.

answer: 31, 5556. 952 seconds
