5. in 1947 bob feller, a pitcher for the cleveland indians, threw a baseball across the
plate at 98.6 mph or 44.1 m/s. for many years this was the fastest pitch ever measured.
if bob had thrown the pitch straight up, how high would it have gone?

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

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.
