Question

A table clock has its minute hand 4 0 cm long Find the average
velocity of the tip of the minute hand (a) between 6 00 a m to 6 30
a m and (b) between 6 00 a m to 6 30 p m

Dear Student,

Please find below the solution of your asked query:

(i) Displacement = 8 cm, from 4 cm above the centre at 6:00
AM to 4 cm below the centre at 6:30 AM
8 cm = 0 08 m

Time taken by displacement takes 30 minutes = 1800
seconds

Average velocity = displacement / time
Average velocity = 0 08 / 1800
= 4 44 × 10-5 m/s

(ii) Displacement = 8 cm, from 4 cm above the centre at 6:00
AM to 4 cm below the centre at 6:30 PM
8 cm = 0 08 m

Time taken by displacement 12 5 hours = 45,000
seconds

Average velocity = displacement / time
Average velocity = 0 08 / 45000 = 1 777 ×
10-6 m/s
= 1 78 × 10-6
m/s

Hope this information clears your doubts about the topic

Keep asking!!
