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
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.
