Physics Homework Help Please?
Physics help pleaseee!!!!
Firemen are shooting a stream of water at a burning building. A high-pressure hose shoots out the water with a speed of 24.0 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 3.10 to reach a building 45.0 away. You can ignore air resistance; assume that the end of the hose is at ground level.
I got part A
A.)Find the angle of elevation of the hose. 52.8 degrees
B.)Find the speed of the water at the highest point in its trajectory.
C.)Find the acceleration of the water at the highest point in its trajectory.
D.)How high above the ground does the water strike the building?
E.)How fast is it moving just before it hits the building?
Thanks a lot for your help =D
At the highest point, the vertical component of speed is zero and the vertical acceleration is that due to gravity.
