Amolecule of hydrogen moves at a speed of 115 cm/s. how long will it take to travel the length of a football field (100 yd long)?

Time, t = 79.51 seconds            

Explanation:

Given that,

Speed of the hydrogen molecule, v = 115 cm/s = 1.15 m/s

Length of a football yard, d = 100 yd = 91.44 m

Let t is the time taken to travel the length of a football field. We know that the time taken can be calculated as :

t = 79.51 seconds

So, the time taken by the molecule to travel the length of a football field is 79.51 seconds. Hence, this is the required solution.

pe = weightxheight = 2000x1000=2,000,000joules
