Question: 1 2 - 9 9 . The missile at A takes off from rest and rises vertically to B , where its fuel runs out

12-99. The missile at A takes off from rest and rises vertically to B, where its fuel runs out in 8 s . If the acceleration varies with time as shown, determine the missile's height hB and speed vB. If by internal controls the missile is then suddenly pointed 45 as shown, and allowed to travel in free flight, determine the maximum height attained, hC, and the range R to where it crashes at D.
