The velocity when the object falls from 84 feet is 73.32 ft/sec
Step-by-step explanation:
The formula is derived from the conversion of energy principle. As the object falls the potential energy changes into kinetic energy. The right formula is:
here,
v represents the velocity
and
h represents the height in feet.
We can plug in the value of height in the formula to get the value of velocity
So, Putting h=84
Rounding off to nearest 100th
v=73.32 ft/sec
The velocity when the object falls from 84 feet is 73.32 ft/sec
