Homework Statement
I need to determine the average speed of a dot on a spinning motor and also the time it takes for teh dot to make on revolution. Using a strobe light I determined I needed to do 3959.2 flashes/min in order to make the dot stay in place. The dot is 6.9 cm away from the center of the motor However, I do not know how to use this in order to calculate time and I am stuck
Homework Equations
average speed = distance traveled (cm)/ time sec
The Attempt at a Solution
Using the 6.90 cm, i determined the circumference is 43.4 cm, and I need to use this in calculating the speed someone. However, I do not know how to use this info and the flashes/min to find either the average speed in cm/sec or the time it takes for one revolution. I need help asap please!
