Question

An object moves in a circular path at 861 rpm. If the radius of its circular path is 9.27 meters, calculate

a) the distance traveled in one complete revolution
d = m

b) the time it takes for one complete revolution
T = seconds

c) the linear speed of the object as it moves in a circular path
v = m/s.

Answer 1

a. d = Circumference = pi*2r = 3.14 * 18.54 = 58.25 m.

b. T = 1min/861rev = 60s/861rev = 0.0697 s./rev

c. V=861rev/min * 58.25m/rev * 1min/60s
=
