Question

A particle is moving on a circular path of radius 10m. If it take 5 sec to complete half motion then its speed will be?​

Answer 1

Answer:

6.28 m/s

Explanation:

perimeter of the circle = $2\pi r$

$2*\frac{22}{7} * 10$

$\frac{440}{7}$

as it covers only half the distance therefore the distance is

$\frac{440}{7}$÷$2$

$\frac{220}{7}$

speed = $\frac{distance}{time}$

speed = $\frac{\frac{220}{7} }{5}$

speed = $\frac{220}{35}$

speed = 6.28 m/s
