Unformatted text preview: the tower and the airplane 16 km west and 12 km north of the tower. As a result of the collision the helicopter was split into two pieces, H 1 and H 2 , of mass m ı = 1000 kg and m 2 = 2000 kg, respectively; the airplane remained in one piece as it fell to the ground. Knowing that the two fragments of the helicopter were located at points H 1 (500 m, 100 m) and H 2 (600 m, 500 m), respectively, and assuming that all pieces hit the ground at the same time, determine the coordinates of the point A where the wreckage of the airplane will be found. Figure 3 4) Two hemispheres are held together by a cord which maintains a spring under compression (the spring is not attached to the hemispheres). The potential energy of the compressed spring is 120 J and the assembly has an initial velocity Vo of magnitude Vo = 8 m/s. Knowing that the cord is severed when θ = 30°, causing the hemispheres to fly apart, determine the resulting velocity of each hemisphere. Figure 4...
