Create an expression for the direction of the car’s average acceleration in terms of v0x, v1x, and v1y during the transition between the horizontal surface and the hill. Express the answer in terms of tan(θ), where θ is the angle of the average acceleration vector relative to the horizontal.

An air standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes. 1-2 isentropic compression 100 kpa and 22°c to 600 kpa 2-3 v=constant heat addition to 1500 k 3-4 isentropic expansion to 100 kpa 4-1 p=constant heat rejection to initial state (a) show the cycle on p-v and t-s s (b) calculate the net work output per unit mass (409 kj/kg) (c) determine the thermal efficiency (47.9%)
