document.write( "Question 1162061: A stone is thrown directly upward from a height of 30 ft, with an initial velocity of 60 ft/sec. The height of the stone, in feet, t seconds after it has been thrown,is given by the function s(t) = -16t^2 + 60t + 30. Based on this model, what is the stone's maximum heights? How long does it take for the stone to reach its maximum height? Answers: 86.25, 1.875, respectively
\n" ); document.write( "
\n" ); document.write( "Can someone help answer the above question if the same equation is set to zero and solve for t to find how long it will take the stone to hit the ground?
