Two cars approach an extremely icy four-way perpendicular intersection. car a travels northward at 26 m/s and car b is traveling eastward. they collide and stick together, traveling at 12o north of east. what was the initial velocity of car b? you may assume that the cars have the same mass. round your answer to one decimal place.

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.

Dis the best answer im sure it is it has to be im positive
