Assume a rocket is launched from a platform that is 20 meters high at angle of 53 degrees. While the rocket still has gasoline, it uniformly accelerates, maintains a launch angle relative to the ground, for four seconds and reaches a velocity of one hundred meters per second starting from rest. You may neglect any air resistance. Part 1: What is the max height the rocket can have before it falls back to ground? Part 2: How much time does...

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...

1 2 A projectile PA is launched from point A towards the east with an initial launch velocity ves and an initial launch angle of 8aA. The impact point of the projectile Pa is a point B in a valley with an ordinate, you, located below the elevation of point A. The launch from point A is instantaneously detected at point B, and a counter projectile Pa ts launched simultaneously towards the west to intercept the incoming projectile PA. Projectile...
