an object moves at a constant rate along a circular path with a radius 10 inches and makes 3 revolutions in 2 seconds.What is the linear velocity,in inches per second,of a point on the edge of the wheel

Respuesta :

given:

radius= 10 inches

3 revolutions in 2 seconds.

to find:

the linear velocity.

solution:

[tex]2\pi \: r = 2 \times \pi \times 10[/tex]

[tex] = 62.85inches[/tex]

[tex](3 \times 62.85)[/tex]

[tex] = 188.57[/tex]

[tex] \frac{188.87}{2} [/tex]

[tex] = 94.28[/tex]

hence, the linear velocity of the object is 94.28 in/s.
