The pipe U-band in the figure attached is connected to a flow system by flexible hoses that transmit no force. The pupse has inner diameter of 3 inches. Water is flowing through the pipe at a rate of 600 gallons/minute. The pressure at point 1 is 5 psig and at point 2 is 3 psig

The acceleration of a marble in a certain fluid is proportional to the speed of the marble squared and is given in SI units) by a=-3.00 v^2 for v greater than 0. If the marble enters this fluidwith a speed of 1.20 m/s, how long will it take before the marble's speed is reduced to half of its initial value?
