What is the speed of the 40 kg box after it has gone up a ramp that's 3 meters tall? The box is initially going at V = 20 meters/second.
Would the equation just be 1/2 mv = 1/2 mv? Or do you incorporate gravitational energy which is = mgh?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
