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. t = s.

Questions involving accelerating objects, including those in free fall, can be solved using three equations   y =  1/2at2 + v0t + y0   v = v0 + at   vf2 = v02 + 2 a (y - y0)   In this case, only the first equation is needed.   Since the object is falling the final height is 0 meters, the initial height is 370 m, and the acceleration is -9.8ms-2   Since the object is dropped, the initial velocity is 0.
So:-4.9t²+370=00=4.9t²-370t²=370/4.9=75.51t=±√75.51=8.7 seconds☺☺☺☺

Can you provide the tape diagram?
