Question

A circular plate is rotating about its own axis at
an angular velocity 100 revolutions per minute.
The linear velocity of a particle P of plate at a
distance 4.2 cm from axis of rotation is
1) 0.22 m/s 2) 0.44 m/s 3) 2.2 m/s 4) 4.4 m/s

Answer 1

Answer:

0.44m/s

Explanation:

ω=100*2π/60

=10π/3

r=4.2cm=0.042m

v=rω

v=(0.042)(10π/3)

=0.44m/s

Answer 2

Hope it helps u guyz❀
