The observation deck of tall skyscraper 370 m above the street. Determine the time required for a penny to free fall from the deck to the street below.

MathMate,
Assuming freefall without airresistance, then use
S=ut+(1/2)gt²
where S=370m, u=initial velocity=0
Solve for t:
370=(1/2)(9.81)t²
It should come out to about 8.5 or 8.6 seconds

(0)0…5(u)0…5=2(9.8)(370)
u=85.15
v=u at
o=85.15 (9.8)(t)
85.15=(9.8)t
