Describe the change in vertical velocity of a horizontally-launched projectile over time. A. As a projectile falls from its initial height, the vertical speed increases over time due to the force of gravity.

B. It is impossible to describe the change in vertical velocity of a falling object because it can't beliuneasured
accurately

C. As a projectile falls from its initial height, the vertical velocity remains constant

D. As a projectile falls from its initial height, the vertical velocity increases over time

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.
