A car with mass of 4000kg accelarates up a road with a slope of 1 in 10, increasing it's speed from 2m/s to 10m/s. It travels a distance of 200m against a frictional resistance of 5kN. Use D'Alembert's Principle to calculate the tractive effort between the driving wheels and road surface.
Consider NH3 vapor acting as a van der Waals gas with coefficients a = 4.169 atm-L2-mol-2 and b = 0.0371 L-mol-1. How much heat must be added to 50.0 g of the gas so that it experiences no change in internal energy as it undergoes isothermal reversib..
