Question

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

Answer 1

"0.758315 sec" is the appropriate choice.

Step-by-step explanation:

The given values are:

Angular speed,

= 29 rad/s

or,

=
`(29)/(2 \pi) \ rps`

Tire rotates,

= 3.5 times

Now,

The time interval will be:

⇒
`\Delta t=(3.5)/((29)/(2 \pi) )`

⇒
`=(2 \pi* 3.5)/(29)`

⇒
`=(21.99)/(29)`

⇒
`=0.758315 \ sec`
