Question

Answer with calculation: A wall clock has a 5 cm long minutes hand. The average velocity of the tip of the hand reaching 6:00 hour to 18:30 hour is?

Answer 1

Answer:

The average velocity of the tip of the hand is 2.2 × 10^-4 cm/ s

Explanation:

total displacement of tip = 2× L = 2× 5cm = 10 cm

the minute hand swap between 6.00 am to 6.30 p.m = 12.5 hrs

i.e 45000 sec

we know velocity = displacement/ time

so, v = 10 / 45000

v = 2.2 × 10^-4 cm/ s
