First Problem
----------------
A flat plate moves normally toward a discharging jet of water at the rate of 3 m/s. The jet discharges water at the rate of .1 m^3/s and at a speed of 18 m/s. (A) Find the force on the plate due to the jet. (B) Compare it with if the plate were stationary.
In part A the V toward each other is 21, 3 to the right, 18 to the left. Just unsure on how to calculate the force which is obviously caused by the plate being hit with the water.
Second Problem
----------------
When at rest, a liquid stands at the same level. A height difference occurs when the system is given an acceleration toward the right. Show that H= aL/g.
Im really poor at proving these, just some helpful steps to start me off would be greatly appreciated
