Problem 6: The thrust produced by a single jet engine creates a force of F = 63000 N. It takes the jet (with a mass of m = 9300 kg) a distance of d = 0.75 km to take off.
Part (a) What is the take-off speed of the jet vt in m/s?
Part (b) How far in meters would you need to depress a giant spring k = 100,000 N/m in order to launch the jet at the same speed without help from the engine?
If the bullet leaves the gun at a speed of 280 m/s, by how much will it miss the target? Illustrate at what angle should the gun be aimed so as to hit the target?
