A camera is set up at the starting line of a drag race, 80 feet from a dragster at the starting line. Two seconds after the start of the race, the dragster has traveled 240 feet and the camera is turning 0.3 rad/s while filming the dragster.
q1 What is the speed of the dragster at this point?
q2 A second camera filming the dragster is located on the starting line 120 ft away from the dragster at the start of the race. How fast is this camera turning 2s after the start of the race (in rad/s)?

Solution
q1) The speed of the dragster is distance from camera * angular velocity = 80*0.3 = \"24 feet/s\" = Answer
q2) The angular velocity = angular speed / distance from camera = 24 ft/s / 120 ft = \"0.3 rad/s\" = Answer
