The circular blade on a saw has a diameter of 7.5 inches and rotates at 2400 revolutions per minute.
a) find the angular speed in radians per sec
b) find the linear speed of the saw teeth ( in feet per sec) as the contact the wood being cut.

formulas--> linear speed= arc length/time= s/t
angular speed= central angle/time

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

answer: the answer is ann
