Question

a particle makes 2complete round in a circular path of radius 10cm in 30 second what is the linear velocity​

Answer 1

Answer

Given :-

• No. of revolutions = 2
• Radius = 10 cm = 0.1 m
• Time taken = 30 sec

To find :-

• Linear velocity :- v

Solution :-

$\boxed{\sf Linear\: speed = \frac{ Total \:distance }{Total \:time }}$

• Total distance $\sf = 2 \times 2\pi r$

$\sf = 2 \times 3.14 \times 0.1$

$\sf = 0.628 m$

• Total time $\sf = 2 \times 30$

$\sf = 60 sec$

$\sf Linear\: speed = \dfrac{0.628}{60}$

$\boxed{\sf\purple{Linear\: speed = 0.014 m/s}}$
