Question

A point on the edge of a flywheel with a radius of 16 cm is rotating at a rate of 10 radians per second. What is the linear speed of a point on its​ rim, in centimeters per​ minute?

Answer 1

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply.

Scenario 1:

Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects.

Answer 2

Answer:

9600 cm/min

Explanation:

Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.

10 radians per second divided by 2π is the number of revolutions per second.

So multiply that times the circumference and that's the distance the point has traveled.

let the linear speed of the spot be v

$v= \frac{10}{2\pi}\times2\pi\times16= 160cm/sec$

therefore, v= 160×60= 9600 cm/min
