16.1. The cart has mass M and is filled with water that has a mass mo. If a pump ejects water
through a nozzle having a cross-sectional area A at a constant rate of vo relative to the cart,
determine the velocity of the cart as a function of time. What is the maximum speed
developed by the cart assuming all the water can be pumped out? Assume the frictional
resistance to forward motion is F and the density of water is p.
16.2 A block of mass 10 kg is subjected to a force F(t) at an angle 30° from the horizontal that is
at a constant 12 N for 3 seconds and is suddenly increased to 18 N afterwards. A constant 1 N force
acts on the block as shown as well. The static and kinetic friction coefficients between the block
and the ground is 0.15 and 0.10, respectively. Determine the magnitude and direction of the
velocity of the block after 5 seconds.

The topping cycle is a gas-turbine cycle that has a pressure ratio of 8. Air enters the compressor at 300 K and the turbine at 1300 K. The isentropic efficiency of the compressor is 80%, and that of the gas turbine is 85%. The bottoming cycle is a simple Rankine cycle operating between the pressure limits of 7 MPa and 5 kPa. Steam is heated in a heat exchanger by the exhaust gases to a temperature of 500°C and the isentropic efficiency of the turbine is 90 %. The exhaust gases leave the heat exchanger at 450 K.
