Aperson is walking in a straight line for 10 s. the person has an initial position that is negative with respect to a chosen origin, and their velocity is also negative during the entire 10 s. at the end of 10 s, is the person closer to or further from the origin than they were originally? explain.

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%)
