A Body With Mass 10kg Moves Around a Circular Path with Radius 5cm.. If the body takes 2min to Complete 1 Revolution... Then Find The Speed Of The Body​

Answer 1

Answer:

speed when moving on a circle

$\frac{2\pi \times r}{t} \\ = \frac{ 2\times \frac{22}{7} \times 5 }{120} \\ = \frac{2 \times 22 \times 5}{120 \times 7 } \\ = \frac{220}{840} \\ = \frac{11}{42}$

= 0.26 cm/s
