Question

a table clock has its minute hand 4 cm long. the average velocity of the tip of the minute hand between 6.00am to 6.30pm is

Answer 1

Displacement = 2 * R

                        = 2 * 4

                        = 8cm

                         = 0.08 m

Time between 6 am and 6:30 pm = 12 hrs and 30 minutes i.e 45000s.


So, average velocity = 0.08/45000

                                   = 1.77 * 10^-6


Hope this helps!
