How do you determine the acceleration of an object?

Question options:

Subtract the starting velocity from the ending velocity

Determine the average velocity and divide by the distance traveled

Multiply the change in velocity by the time interval

Divide the change in velocity by the time interval

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).
