Question 408637
If a ball is dropped from 214 ft above the ground, how long does it take to reach ground level?
(Round your answer to two decimal places.)
:
The equation for this is: -16t^2 + 214 = 0 (ground = 0)
-16t^2 = -214
divide both sides by -16
t^2 = 13.375
t = {{{sqrt(13.375)}}}
t = 3.657 ~ 3.66 seconds
