Question

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

Answer 1

given:

radius= 10 inches

3 revolutions in 2 seconds.

to find:

the linear velocity.

solution:

`2\pi \: r = 2 * \pi * 10`

`= 62.85inches`

`(3 * 62.85)`

`= 188.57`

`(188.87)/(2)`

`= 94.28`

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