A particle travels in a circle of radius 82 cm with a centripetal acceleration of 4.7 m/s\(^2\). How long does the particle take to complete one revolution?

Asked by vivinguyen97

Answer (3)

acceleration = r w² radius r = 0.82 meter angular velocity w
4.7 = 0.82 w² So w = 2.394 radians / sec Time period T = time duration for completing one revolution = 2 π / w = 2π / 2.394 = 2.624 seconds

Time, T = 2.62 seconds ;

The time taken for the particle to complete one revolution is approximately 2.62 seconds, calculated using its centripetal acceleration and radius. We find the linear velocity from the centripetal acceleration and then calculate the circumference to determine the time. Thus, the final result is about 2.62 seconds per revolution.
