Question

One of the fastest pitches ever thrown in Major League Baseball was by Aroldis Chapman and had a velocity of 105.1 miles/hour. How many seconds did it take this pitch to travel the 60 feet and 6 inches from the pitcher's mound to home plate? (1 mile = 5280 feet)

Answer 1

Speed of ball=$105.1 \space miles/hr=\frac{105.1 \times 5280}{3600} feets/sec$ =$154.15 feets/sec$

Distance traveled=$60 \space feet +6 \space inches=60.5 \space feets\space( 6 \space inches=0.5 feet)$

Time taken$=\frac{distance}{speed}=\frac{60.5}{154.15}$ $=0.392 sec$
