Awater balloon slingshot launches its projectiles essentially from ground level at a speed of 25.5 m/s . (you can ignore air resistance.)

a: at what angle should the slingshot be aimed to achieve its maximum range?

b: if shot at the angle you calculated in part a, how far will a water balloon travel horizontally?

c: for how long will the balloon be in the air?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
