" we can find the speed of the penny as instantaneous rate of change of height of penny when it hits ground. "
Details:
If you have been given the equation
v²-u²=2aH
then
H=distance, and
velocity=v (u=constant=0)
If you express v as a function of H, which you have already done with numbers, then you get the speed of the coin (ignoring air resistance) as a function of H.
if a penny is dropped from the top of a 320 ft. building, how fast will it be moving when it hits the ground?
So we can find the speed of the penny as instantaneous rate of change of height of penny when it hits ground.
Instantaneous rate of change of y with respect to x is dy/dx?
