Aparticle travels in a circle of radius 76 cm and completes one revolution in 4.5 s. what is the centripetal acceleration of the particle?

Acceleration,

Explanation:

Given that,

Radius of circle, r = 76 cm = 0.76 m

Time period of revolution, t = 4.5 s

To find :

Centripetal acceleration of the particle.

Solution,

Let v is the velocity of particle. On the circular path velocity of a particle is given by :

The centripetal force on the circular path is given by:

So, the acceleration of the particle is .

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
