I need to figure out if a baseball is thrown upward with an initial velocity of 110 feet per second (75 miles per hour) and it is released 5 feet above the ground. Its height h after t seconds is given by h= -16t2 +110t +5. After how many seconds does the baseball reach a maximum height? Estimate this height.

The baseball reaches the maximum height after approximately _ sec from the time its being thrown upward.
