A stone is thrown straight upward, slightly out from the corner of the roof of a building. The initial upward speed of the stone is 20 m/s as it leaves the hand of the thrower. Assume that the stone is 50.0 m above the ground when it is released.
Assume that the initial position of the stone is at y = 0 and that positive y is up
Find the following:
1. The time needed to reach max height
2. The max height
3. The time needed to get back to initial height
4. The velocity of the stone in #3
5. The height of the stone at 5 seconds
6. The velocity of the stone just as it hits the ground

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
