Question

A friend of yours claims to be able to ride a bicycle 20 feet per second, is this a reasonable

speed for a bicycle? Help

Answer 1

No and yes

Explanation:

If the bike is at a sudden hault (A FULL STOP) its physically impossible for the sudden speed of his weight and laws of inertia to pull him forwar that quick.

NOW - if the bike is already in motion and going downhill the gravitational down force will haul his speed at 45MPH and would make him reach the lenght of 66feet per second.
