a) sqrt(2 g H),
where H = 40 m.
b) g*H per unit mass
c) zero. It temporarily stops moving at maximum height (if aimed straight up)
You don't need the liter/minute rate
A fire hose can project water at a rate of 6.00x10^2 litres per minute to a height of 40.0m. Find:
a) the velocity with which the water leaves the tube
b) the kinetic energy of the water as it leaves the hose
c) the kinetic energy of the water at 40.0m.
