Question

Iii. aroldis chapman holds the world record for fastest baseball pitch at 105.1 mph (169 km/h). the distance from the pitcher’s mound to home plate is approximately 60 feet (~18 meters). assuming constant velocity, how much time would a batter have to react to chapman’s world record pitch?

Answer 1

Answer:

A batter would have to strike the ball within 2.56 seconds.

Explanation:

Speed = 105.1 mph or, 169 km/hr

1 km/hr = 5/18 m/s

= 169 km/hr = [169*5/18] m/s

= 46.94 m/s

Distance = 60 ft (approx.)

1 ft = 30.45 cm = 0.3045 m

60 ft = [60*0.3045] m

= 18.27 m

Speed = Distance/Time

= 46.94 = 18.27/T

= 2.56 s = T

Hope this helps.
