An object is launched at a velocity of 36 m/s in a direction making an angle of 40° upward with the horizontal.
What is the magnitude of the velocity when it hits the ground?
Hint: This is a conceptual vector problem.
please help me

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.

It would stay the same
