One of the many random useless factoids that I carry around
in my head is the factoid that 60 miles per hour is equivalent
to exactly 88 feet per second.
So in three seconds at that speed, you would cover exactly
(3 x 88) = 264 feet.
A, chemical bondings would yield a positive enthalpy change, thus endothermic.
Sliding and Static.
Would be the right one here.
