Aball at the end of a string of 2.2m length rotates at
aconstant speed in a horizontal circle. it makes 5.8 rev/s. what
isthe frequency of motion( ans. in

The frequency of motion is 5.8 Hz.

Explanation:

frequency of motion of any object is defined as the number of times the object repeats it's motion in 1 second.

mathematically frequency equals

where,

'T' is the time it takes for the object to complete one revolution. Since it is given that the ball completes 5.8 revolutions in 1 seconds thus the time it takes for 1 revolution equals

Hence

thus the frequency equals
