Question

A wheel of radium 40cm is turning about a fixed axis through the centre of a 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 1

HEY MATE HOPE U ARE WELL..!

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
