Question

a body moves along circular path of radius 10 M and the coefficient of friction is 0.5 what should be the angular velocity in Radian per second if it is notto alipfromthe surface g=9.8
​

Answer 1

Answer:

The angular velocity is 0.7 rad/sec.

Explanation:

Given that,

Radius = 10 M

Coefficient of friction = 0.5

We need to calculate the  velocity

Using formula of velocity

$v=\sqrt{\mu\times r\times g}$

Put the value into the formula

$v=\sqrt{0.5\times10\times9.8}$

$v=7\ m/s$

We need to calculate the angular velocity

Using formula of angular velocity

$v = r\omega$

$\omega=\dfrac{v}{r}$

Put the value into the formula

$\omega=\dfrac{7}{10}$

$\omega=0.7\ rad/sec$

Hence, The angular velocity is 0.7 rad/sec.
