The top speed of a tortoise on the ground is 5 mph. Morris, the tortoise, being in top physical shape, propels himself off of a horizontal cliff top which is 8 m above Loch Ness in the highlands of Scotland.

(a) How far does Morris travel horizontally before he goes swimming with Nessie?
(b) What is the magnitude and direction of the velocity of Morris as he enters the water?

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).
