Ared ball is thrown down with an initial speed of 1.1 m/s from a height of 28 meters above the ground. then, 0.5 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 24.4 m/s, from a height of 0.9 meters above the ground. the force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. how long after the red ball is thrown are the two balls in the air at the same height?

What are the theoretical properties of a gas at a temperature of 0 kelvin?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
