Suppose there is a CD that is rotating at a rate of 450 rpm. Suppose that there is a speck of dust that is 4 cm away from the center of the CD. What is the total distance traveled by that speck of dust in 2 minutes

Respuesta :

Answer:

[tex]d=226.2m[/tex]

Step-by-step explanation:

From the question we are told that:

Rotational Speed [tex]N =450rpm[/tex]

Time [tex]T=2min=>120sec[/tex]

Radius [tex]r=4cm=>0.04m[/tex]

Generally the equation for Distance Traveled is mathematically given by

 [tex]d=\omega*2\pi r*T[/tex]

 [tex]d=450*2*\pi*0.04*2[/tex]

 [tex]d=226.2m[/tex]
