An object is dropped from a bridge and allowed to freefall to the ground. the height of the object over time can be modeled using h(t) = 144 – 16t2. how many seconds will it take the object to reach the ground? second(s)

t = 3 seconds

Step-by-step explanation:

We have the equation, as a function of time, that describes the height of the object that is dropped from the bridge.

The equation is:

Where t is the time in seconds and h is the height in feet.

To know how long it takes the object to fall to the ground we do h (t) = 0 and solve for t.

So:

We take the positive solution.

Therefore the object takes 3 seconds to reach the ground

answer: haha (: i’ll go see what it is
