Question

A robotic basketball player tosses a ball upward from a height of 7 feet, at an initial speed of 111 feet per second.
The height of the ball is modeled by the equation: h=−16t2+111t+7, where h is the height above the ground in feet and t is the time measured in seconds.
How long does it take for the ball to hit the ground?

Answer 1

just solve for t when h=0
good old algebra I

Answer 2

7sec
