Correct Answer : Long duration
Explanation : Inflight correction maneuvers are typically short duration maneuvers. They are intermittent (pulsing) operations performed with low thrust.
Correct Answer : Option (C) : 52.36 m/s
Explaination : Pitch rate q = V/RThen, V = qR = 20 x π/180 x 150 = 52.36 m/s.
Correct Answer : Option (C) : 1.525 hrs
Explanation : T=2π(R0+h)3/2/√μ= 2×3.14x(6728000)3/2/(3.986×1014)= 1.525 hrs.
Correct Answer : Option (D) : Unguided rocket projectiles
Explanation : Unguided rocket projectiles can be given a rotation about its longitudinal axis by means of inclined fins or smaller rocket nozzles to stabilize it. This is an example of spin stabilization.
