swer the following angular speed questions. (Enter your answers using exact values.) (a) A wheel of radius 25 ft. is rotating 13 RPM counterclockwise. Considering a point on the rim of the rotating wheel, what is the angular speed win rad/sec and the linear speed v in ft/sec? w= 1.36 V= rad/sec x ft/sec (b) A wheel of radius 9 in. is rotating 45/sec. What is the linear speed v, the angular speed in RPM and the angular speed in rad/sec? v = 7.06 in/sec X 83 W= rpm rad/sec (c) You are standing on the equator of the earth (radius 3960 miles). What is your linear and angular speed? V= 13 mph rad/hr (d) An auto tire has radius 12 inches. If you are driving 65 mph, what is the angular speed in rad/sec and the angular speed in RPM? rad/sec @= w= 905 rpm
