How do you graph motion in physics? how do you graph motion in physics? i've seen problems state that an object is in free fall or that it was thrown upward and hits the ground, but i don't know how to graph them. if acceleration is gravity, i know that -9.8 should be in the equation somewhere, but i don't know how to incorporate that number with an initial velocity and height.

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).
