The parking brake on a 1000 kg Cadillac has failed, and it is rolling slowly at 1.00 mph, towards a group of small children. Seeing the situation you realize you have just enough time to drive your 2000 kg Volkswagon head on into the Cdillac and save the children. With what speed should you impact the Cadillac to bring it to a halt?

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.
