Solve the all given parts of following question:
Question: Firemen are shooting a stream of water at a burning building. A high-pressure hose shoots out the water with a speed of 27.0m/s as it leaves the hose nozzle. Once it leaves the hose, the water moves in projectile motion. The firemen adjust the angle of elevation of the hose until the water takes 3.30s to reach a building 45.0m away. You can ignore air resistance; assume that the end of the hose is at ground level.
Part A: Find the angle of elevation of the hose?
Part B: Find the speed of the water at the highest point in its trajectory.
Part C: Find the acceleration of the water at the highest point in its trajectory.
Part D: How high above the ground does the water strike the building?
Part E: How fast is it moving just before it hits the building?
Please explain clearly with details so that I can follow.
