Find the speed of a point on the rim of a 24cm diameter fly wheel which is turning at 2800 revolutions per minute. Give your answer in meters per second.
Circumference of circle =2 Pi r
=2×3.142x12=75.408
75.408 in 2800 revolutions per minute=75.408×2800
=211142.4÷100=2111.424
Speed= Distance÷Time
S=2111.424÷60
S=35.1904
S=35.2m/s
Answer is 35.2 m / s
Answer is 35.2m /s
Find the citcumfrence
2€r=2*3.14*12
75.36cm
75.36/2800
37.15m
Answer is 35.2 m/s

do the circumference. then find the revolution.then the answer will come. the answer is 35.2m/s
C = pi * D = 3.14 * 0.24m = 0.754 m.= Circumference.
V=2800rev/min * 0.754m/rev * 1min/60s = 35.2 m/s.
diameter 24 cm
so radius 12
