Mathematics
A stone is dropped from a 196-foot platform. Use the formula h=−16t2+v0t+196 to determine how many seconds it will take for the stone to hit the ground. (Since the stone is dropped, v0=0.) Round your answer to the nearest tenth.

Ответ:
16t^2 = 196
t^2 = 196/16
t^2 = 12.25
t = sqrt(12.25)
t = 3.5
So roughly 3.5 seconds
