Question

4.
A merry-go-round with radius 2 m is rotating about a vertical axis at the rate of 60 rev/minute.
If a child is sitting at its centre of rotation, the child's linear speed is

Answer 1

Answer:

linear speed(v)=rw

where w=angular speed in radian per second

w=60 rev/min=60×2(3.14)÷60×60=1.046

putting the values in formula we get

v=2×1.046=2.093m/s
