Question

The length of the minute hand of the clock is 14cm. Calculate the speed with which the tip of the minute hand moves

Answer 1

Speed of the tip of the minute hand=V=0.0244 cm/s

Step-by-step explanation:

The angular velocity of the minute hand is given by

`\omega= (2\pi)/(T)`

T= time period of the minute hand=60 min=3600 s

so ω= 2 π/3600 rad/s

Now linear velocity v= r ω

r= radius of minute hand=14 cm

so v= 14 (2 π/3600)

V=0.0244 cm/s
