The equation y=-16t^2+120 can be used to represent the fruits height above the ground, where t represents time in seconds after she threw the apple. How long did it takr the apple to hit the ground? round to the nearest hundredth.

Accepted Solution

A:

to hit the floor means the height is 0.

-16t²+120=0

-16t²=-120

t²=7.5

t=2.74

-16t²+120=0

-16t²=-120

t²=7.5

t=2.74
