A320 g bird flying along at 7.0 m/s sees a 12 g insect heading straight toward it with a speed of 30 m/s (as measured by an observer on the ground, not by the bird). the bird opens its mouth wide and enjoys a nice lunch. what is the bird's speed immediately after swallowing?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
