Question

The length of minute hand in a pendulum clock is 10cm the speed of tip of the hand is (in m/s)

Answer 1

Answer:

0.01 m/s

Step-by-step explanation:

In 1 hour the minute hand rotates 2π radian so, in 1 second = π/1800 radian. So, Angular velocity = π/1800 rad/sec.

Radius of minute hand = 10 cm = 0.1 m.

Velocity of minute hand = Angular Velocity × radius ..

Therefore v = π/1800 × 0.1

= 0.01 m/s (1π radian = 180°)....

Hope it helps....

Answer 2

Answer:

answer

0.1m/s

r of 1 min hand -10cm=o.1m

v × r

π/1800×0.1

=0.01m/s(1πradian= 180*)
