Question

Suppose you are involved in designing a hypersonic missile. For the first test flight, the missile was taken to a launching pad and was put on a point A, as in the figure below. The missile at A took off from rest and rose vertically to B, where its fuel system malfunctioned and stop working. It took the missile 8 s to reach from A to B with a variable acceleration. The time vs acceleration curve is shown in the figure as well. Now answer the following questions: a (m/s)

Answer 1

ho ho а (m3 40 (a, .) - Coo) (0,1) - 0,3) ,4 кг оb 1 1 a-t - , , ( - )) o - 0 1 - 0 1 )

r= fadt Velocity & Q = 40 + valadt v=uotat = x 2 + c = 20 € + At t=0 = 20 - 20 x ² + 10 20 7 r = 20 x²

At t=8 sec, r=ve. Vo = 20 x 2² to = 160 /s heigne = Svat naf so te at At to h=0 Inzhg i h= 20 + At t=8 sec no eo x 8 = [ho = 426.6 mes ! 20 (BR-426.6 mts
