A stone in a sling spins in uniform circular motion. If the stone makes 2 revolutions in 3.41 seconds, what is the angular speed of the ball (in radians/s!)?

A Stone In A Sling Spins In Uniform Circular Motion If The Stone Makes 2 Revolutions In 341 Seconds What Is The Angular Speed Of The Ball In Radianss class=

Sagot :

First we need to change the revolutions

1 rev= 2pi

therefore

2 rev =4pi

The formula of angular velocity is

[tex]\omega=\frac{\theta}{t}[/tex]

where theta is the displacement in radians and t is the time in our case

theta=4pi

t=3.41

[tex]\omega=\frac{4\pi}{3.41}=3.69\text{ rad/s}[/tex]

ANSWER

3.69 rad/s
