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...

Problem 3: A 7200-kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.20m/s? and feels no appreciable air resistance. Whe it has reached a height of 555 m, its engines suddenly fail; the only force acting on it is now gravity. a. What is the maximum height this rocket will reach above the launch pad? b. How much time will elapse after engine failure before the rocket comes crashing down to the launch pad,...

2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...

1: A projectile is launched from the top edge of a cliff of height h. The launcher is to deliver a package to some hikers stranded in the valley below. From GPS readings it is known that the hikers are a distance d (known) from the base of the cliff. If the projectile launcher is pointed at an angle θ (known), calculate the speed at which the projectile should be launched. 2: For this problem the heights are low enough...
