Ariel skiing involves speeding down a steep ramp that curves sharply upward at the end to launch the skiers into the air. Once airborne skiers twist and turns into Contacts combinations to score points in the competition. Consider an aerial launch ramp that has a final launch slope of 52.9° above the horizontal. Given this angle a skier flies to 17.1 m above the end of the ramp. From this information determine the skiers launch speed

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1

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).
