Question

calculate the speed of tip of minute hand whose length is 7cm​

Answer 1

Answer:

The answer is 1.2*10^-4m/second

Explanation:

Give that :

radius = 7cm =0.07 m

circumference = 2πr =2π(0.07)

=0.4396 m

time taken = 60 minutes = 3600 seconds.

speed = 0.4396/3600= 1.2*10^-4m/second.

radial speed= 2πr/3600 rad/second.
