The missile at A takes off from rest and rises vertically to B , where its fuel runs out in 8 s. The acceleration varies with time as shown. Suppose that a 1 = 39 m/s2 . By internal controls the missile is then suddenly pointed 45? as shown, and allowed to travel in free flight.

1. Determine the missile's speed vB .
2. Determine the missile's height hB .
3. Determine the range R to where the missile crashes at D .
4. Determine the maximum height attained, hC .
