Question 1192073
A baseball is dropped from a stadium seat that is 81 feet above the ground. Its height s in feet after t seconds is given by ​s(t)=81-16t^2. Estimate to the nearest tenth of a second how long it takes for the baseball to strike the ground.
=======================================
​s(t)=81-16t^2 = 0
Solve for t, ignore the negative value.
