The angle covered per minute is radians. ? The airspeed of the plane is miles per hour. ? A camera in the control tower is taping the plane\'s flight. The speed that the camera must turn to keep up is radians per second. ? Solution a) revolutions --0.75 rev/min In radians --- 0.75*2pi/min = 4.71 rad/min b) linear velocity = angluar vel. *radius = 4.71*4.1 = 19.32 miles/hr c) camera would rotate at same speed of plane - 4.71 rad/min to track the plane Total angle rotated = angular vel*time =4.71*10 = 47.1 radians.
