A car tire rotates with an average angular speed of 29 rad/s. In what time interval will the tire rotate 3.5 times? ​

Respuesta :

Answer:

"0.758315 sec" is the appropriate choice.

Explanation:

The given values are:

Angular speed,

= 29 rad/s

or,

= [tex]\frac{29}{2 \pi} \ rps[/tex]

Tire rotates,

= 3.5 times

Now,

The time interval will be:

⇒  [tex]\Delta t=\frac{3.5}{\frac{29}{2 \pi} }[/tex]

⇒       [tex]=\frac{2 \pi\times 3.5}{29}[/tex]

⇒       [tex]=\frac{21.99}{29}[/tex]

⇒       [tex]=0.758315 \ sec[/tex]
