I need help with the following angular speed questions

Answer the following angular speed questions. (Enter your answers using exact values.) (a) A wheel of radius 23 ft. is rotating 11 RPM counterclockwise. Considering a point on the rim of the rotating wheel, what is the angular speed w in rad/sec and the linear speed v in ft/sec? w=|1.15192 rad/sec v v= ft/sec X (b) A wheel of radius 5 in. is rotating 45/sec. What is the linear speed v, the angular speed in RPM and the angular speed in rad/sec? v =[3.926991 in/sec 4 W= rpm A =|0.785398163 rad/sec v (c) You are standing on the equator of the earth (radius 3960 miles). What is your linear and angular speed? v= mph X _| & W= 12 rad/hr v (d) An auto tire has radius 12 inches. If you are driving 60 mph, what is the angular speed in rad/sec and the angular speed in RPM? w=88 rad/sec v w= rpm X
