Compute for the frequency?

Question

the time for 10 revolutions is 5.08sec. what is the frequency (rev/s)? solution please

Answer 1

time=rps=10x2(3.142)/5.08=12.37rps

f=1/T,where T is time,

then, f=1/12.37=0.08 hz

for frequency in rev/s unit, then f=0.08x2(3.142)/12.37=0.04rps

rps=rev per second

Answer 2

Rev/Sec = Revolutions/time = 10/5.08 = 1.9685 Rev/sec

Answer 3

Divide 10 by 5.08.

10 rev / 5.08 sec =

(10/5.08) rev / (5.08/5.08) sec =

(10/5.08)rev / 1 sec
