While trying out for the position of pitcher on your high school baseball team, you throw a fastball at 87.6 mi/h toward home pl
ate, which is 18.4 m away. how far does the ball drop due to effects of gravity by the time it reaches home plate? (ignore any effects due to air resistance and assume you throw the ball horizontally.)?

Answer:
539.19 m/s , 459.83 m/s , 2156.78 m/s
Explanation:
The formula for the rms speed is given by
Where, R be the gas constant, T be the absolute temperature and M be the molecular mass of the gas
R = 8.314 in SI units
T = 100°C = 100 + 273 = 373 K
For Oxygen:
M = 32 g = 0.032 kg
vrms = 539.19 m/s
For carbon di oxide:
M = 44 g = 0.044 kg
vrms = 459.83 m/s
For hydrogen:
M = 2 g = 0.002 kg
vrms = 2156.78 m/s
