A table clock has its minutes hand 4 cm long. Find the average velocity of the tip of the minute hand between 6.00 AM to 6.30 AM.

Answer»

The minute hand of a clock comes into a straight line from 6.00 AM to 6.30 AM.

Hence the displacement of the minute hand S = 2 x 4 = 8 cm

Time = 30 minutes = 1800 sec.

Average velocity=\(\frac{Displacement}{time}\)=\(\frac{8 cm}{1800 sec}\)=0.0044 cm/sec
