A football is thrown vertically upwards and reaches its maximum height after 4.50 seconds.
a. What is the acceleration of the football at its maximum height? [1]
b. What is the initial velocity of the football? [2]
c. What is the maximum height reached by the football? [2]
d. Use the graph paper at right to sketch a qualitative velocity-time
graph for the motion of the ball as it comes up AND back down.
You do not need to fill in numbers, but you may if it helps. [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).
