Observe a bouncy collision (also known as an elastic collision) and discuss whether or not the outcome was what you predicted it to be. Use carts with spring plungers or magnets. If not, draw a new sketch in the space that follows with arrows indicating the magnitudes and directions of the velocities. What is the apparent relationship between the final velocities and

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.
