Question

Calculate the angular velocity and linear velocity of a tip of minute hand of length $10cm$.

Answer 1

$\omega =\frac{2\pi \times d}{t}$

$\Rightarrow \omega =\frac{2\pi }{3600}\times 10\times {10}^{-2}$

$\Rightarrow \omega =1.745\times {10}^{-3}$

$v=\omega \cdot d$

$\Rightarrow v=1.745\times {10}^{-3}\times 10\times {10}^{-2}$

$\Rightarrow v=1.745\times {10}^{-4}$ $m/s$
