Water stands at a depth H in a large, open tank whose sidewalls are vertical. A hole is made in one of the walls at a depth h below the water surface.

a) at what distance R from the foot of the wall does the emerging stream strike the floor?

b) How far above the bottom of the tank could a second hole be cut so that the stream emerging from it could have the same range as for the first hole?

An elevator (mass 4850 kg) is to be designed so that themaximum acceleration is 0.0600g. What is the maximum and the minimum forces the motor should exert on the supportingcable?

I already know how to find the maximum force (just multiplyingthe maximum acceleration by the mass), but I've got no clue as tohow to find the minimum acceleration when no minimum accelerationhas been found.

After grabbing some food from the cafeteria, Ray trips causing his food to go up in the air before hitting the ground. The parabolic path of his food tray can be modeled by the function ℎ(𝑡) = − 0. 2𝑡 , where h is 2 + 0. 4𝑡 + 1. 6 the height in meters after t seconds. a) What is the maximum height of the tray?

If Ray manages to catch the tray at the same height from which the tray flew out of his hands, how long is it in the air?
