A carnot engine operates between a hot reservoir at 310 K and a cold reservoir at 280 K. If it absorbs 500 J of heat at the hot reservoir, how much work (in joules) does it deliver?
A bullet leaves a standard 45-caliber pistol (5.0-in. barrel) at a speed of 262 m/s. If it takes 1 ms to traverse the barrel, determine the average acceleration experienced by the 16.2-g bullet within the gun and after that compute average force e..
