<u>Answer:</u>
The ball fall vertically 2.69 ft by the time it reached home plate 60.0 ft away.
<u>Explanation:</u>
Fastest recorded pitches major-league baseball, thrown by nolan ryan in 1974 = 100.8 mi/hr = 44.8 m/s
The horizontal distance to home plate = 60.0 ft = 18.288 m
We have the horizontal velocity = 44.8 m/s
So time taken = 18.288/44.8 = 0.408 seconds.
The distance traveled by baseball vertically is found out by equation 
Here u =0m/s, a = 9.81 
and t = 0.408 s
Substituting
So vertical distance traveled = 0.82 m = 2.69 ft
The correct answer would be answer c ........
Using the equation KE=1/2mv^2, plug in the numbers and solve for KE
The correct option is D.
The Quantum theory states that both light and matter are made up of small particles that possess wavelike and particle like properties. This is described as the dual nature of light and matter. Light is made up of photons while matter is made up of electron, proton and neutron. The two can behave as both waves and particles.
