Question

he length of a minute hand of a clockis 7 cm. Find out the average speed and average velocity (in cm/min) of the tip of the minute hand when it movesduring a time interval from 3: 15 pm to 3: 45 pm?

Answer 1

Answer:

where, r = length of minute hand

θ = angle moved by minutes hand

distance covered= 7×3π/2

=32.98π

velocity=distance/time

=32.98/45×60

$43.97 \times {10 }^{ - 5} {ms}^{ - 1}$
