Aminivan travels straight north in the right lane of a divided highway at 28.0 m/s. a camper passes the mini- van and then changes from the left lane into the right lane. as it does so, the camper's path on the road is a straight displacement at 8.50° east of north. to avoid cutting off the minivan, the north-south distance between the camper's back bumper and the minivans front bumper should not decrease. (a) can the camper be driven to satisfy this requirement? (b) explain your answer

I) a gas contained within a piston-cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 10 bar, v1 = 0.1 m3 , u1 = 400 kj and p2 = 1 bar, v2 = 1.0 m3 , u2 = 200 kj: ' process a: process from 1 to 2 during which the pressure-volume relation is pv = constant. ' process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2. kinetic and potential energy effects can be ignored. for each of the processes a and b, a) sketch the process on a p-v diagram. b) evaluate the work, in kj. c) evaluate the heat transfer, in kj.(ans : qb,12 = -65.0 kj)
