22. Linear & Angular Velocity Find the angular velocity in R.P.M. of a microwave turntable if it turns through an angle of 36° each second.
23. Linear & Angular Velocity The cable lifting a garage door turns around a pulley at a rate of 20 cm per second. How long will it take to lift the door 2.2 meters?
24. Linear & Angular Velocity Find Joes linear velocity (in feet per min) on a Ferris Wheel turning 4 R.P.M. with a radius of 30 feet.
25. 5 Formulas to KNOW/MEMORIZE:
26. Variables: s, r, ?, A, v, t, ? Arc Length: s = r ?
Area: A = ˝ ? r2
Def: Linear Velocity: v = s / t
Def: Angular Velocity: ? = ? / t
Relationship of v & ?: v = r ?
? must be in RADIANS/time!
Use RADIANS
