A 10,000-lb helicopter A was traveling due east at a speed of 190 mi/h and an altitude of 2400 ft when it was hit by a 13,000-lb helicopter B. As a result of the collision, both helicopters lost their lift, and their entangled wreckage fell to the ground in 12 s at a point located 1600 ft east and 400 ft south of the point of impact. Neglecting air resistance, determine the velocity components of helicopter B just before the collision.
