Two dart guns both shoot the same darts. One is noted to shoot its dart with a velocity 4 times greater than the other dart gun. How would the kinetic energy of the darts coming out of the faster gun compare to that of the weaker gun?

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
