A ball is thrown vertically from the top of a house 112 ft high. Its equation of motions is `s = – 16t^2 + 96 t` where s ft. is the directed distance of the ball from the starting point at tsecs. Then the maximum height in feet attained by the ball and the time in seconds it takes to hit the ground are respectively
