Question

calculate the angular velocity and linear velocity of tip of minute hand of length 10 centimetre ​

Answer 1

SOLUTION.

As we know. that Angular velocity is the rate of change of angle of a particle when travel in a circular path.

Minute hand cover 360° Or 2π angle in 1min Or 60sec so angular velocity of the minute hand is given as......

w = θ/t

w = 2π/60

w = π/30

And the relation between angular velocity and linear velocity is given as....

v = wr

r is the radii of the circular path

For minute hand you give radii = 0.1m

V = (π/30)0.1

V = π/300
