The length of a minute hand of a clock is 8 cm. Find the displacement and average velocity of the tip of the minute hand when it moves during a time interval from 4:15pm to 4:45pm.
Answers
displacement = 16cm and average velocity = 0.533 cm/min
It has given that the length of a minute hand of a clock , l = 8cm.
we have to find the displacement and average velocity of the tip of the minute hand when it moves during a time interval from 4 : 15 pm to 4 : 45 pm.
minute hand makes 2π angle in 60 minute
so, mind hand makes π angle of 30 minute. i.e., path of minute hand is semicircle.
displacement covered by minute hand, s = diameter = 2 × 8 = 16 cm
average velocity = displacement/time taken
= 16cm/30 min = 0.533 cm/min
