To find out how long it took for the apple to hit the ground, we set y = 0 in the equation:
0 = -16t^2 + 1220
Now, we can solve for t:
16t^2 = 1220
t^2 = 1220/16
t^2 = 76.25
t = √76.25
t ≈ 8.73
Therefore, it took approximately 8.73 seconds for the apple to hit the ground.
Samantha threw an apple out of a window from the tenth floor of her apartment building. the equation y=-16t^2+1220 can be used to represent the fruit's height above the ground, where t represents time, in seconds, after she threw the apple. How long did it take the apple to hit the ground? Round the answer to the nearest hundredth
