Problema Solution
A wheel of radius 40cm is turning about a fixed axis through the center of the wheel at a rate of 2 revolutions per minute. Calculate the:
a) angle through which the wheel turns in 10 seconds;
b) distance moved by a point on the rim in 10 seconds.
Answer provided by our tutors
as the wheel radius is 40cm
a. in 10 sec it rotate 2/60*10=1/3 revolution
thus, angle it made=360/3=120
b. distance=1/3*40=40/3 cm
