A freefall ride is dropped from rest and falls for 2.1 seconds. Assume the top of the ride is the reference point.

-Calculate the distance the ride falls.

-Calculate the final velocity of the ride.

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.
