An object is dropped from 39ft below the tip of the Petronaas Twin Towers in Kuala Lumpur, Malaysia. The height h of the object after t seconds is given by the equation h=-16t+1444. Find how many seconds pass before the object reaches the ground.
All you have to do is put 39 in for h. So you get 39=-16t+1444. And solve.
To find how many seconds pass before the object reaches the ground, we need to determine the value of t when h = 0.
Given the equation h = -16t + 1444, substitute h = 0:
0 = -16t + 1444
Now, let's solve for t by isolating the variable:
16t = 1444
t = 1444/16
Dividing 1444 by 16, we get:
t = 90.25
Therefore, it will take approximately 90.25 seconds for the object to reach the ground.
