An 0.80-kg block is held in place against the spring by a 67-n horizontal external force (see the figure. the external force is removed, and the block is projected with a velocityv1 = 1.2 m/s upon separation from the spring. the block descends a ramp and has a velocity v2 = 1.9 m/s at the bottom. the track is frictionless between points a andb. the block enters a rough section atb, extending toe. the coefficient of kinetic friction over this section is 0.39. the velocity of the block isv3 = 1.4 m/s atc. the block moves on tod, where it stops. the spring constant of the spring is closest to

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
