The height h, in feet, of an acorn that falls from the a branch 80 feet above the ground depends on the time t, in seconds, since it has fallen. This represented by the rule h=80-16t^2
Answer: We know that the acorn falls from the height of 25 feet above the ground, it means the initial time when it falls is t = 0. The time when it lands on the ground is t = 1.25
