Unformatted text preview: =75 degrees. It also reports that dr/dt = 40m/sec; d 2 r/dt 2 = 28m/sec 2 ; d /dt =-0.15 radians/second; and d 2 /dt 2 = 0.01 radians/sec 2 . Recall i = e r cos -e sin ; j = e r sin + e cos ; At this moment: What is the horizontal component of the velocity of the airplane? What is the magnitude | a | of the acceleration of the airplane? 3] A 5m long stick that retains contact with the wall at A, and the floor at B, is moving to the right and up. At the pictured instant point B is moving at the constant speed of 1m/sec to the right. What is the speed of A? What is the acceleration of A?...
