  1. Morning/Afternoon!! • Pg. 324 #70 – 76 all • First, we will discuss the test!

  2. Angular and Linear Velocity Motion: Let P be a point on the circumference of the wheel where r is the radius rotating at a constant rate. The angular velocity (speed) of the wheel, in radians per second, is the angle swept out in 1 sec by the line segment from the center of the wheel to the point P on the wheel’s circumference. The linear velocity (speed) of the point P, in feet per second, is the distance P travels in 1 second. • Radian measure can be used to analyze the motion of a point moving at a constant speed along a circular path.

  3. Angular and Linear Velocity A wheel with radius of 18 in. is rotating at 850rpm (revolutions per minute). Determine the following: • The angular speed of the wheel in radians per second • The linear speed in feet per second of a point on the circumference of the wheel.(Hint: 1 rpm = 2π rad./min)
