Question

3. If an object is dropped from a height of 100 ft, the function h(t) = -16f+

Answer 1

Answer:

When t = 25/4 the object his the ground.

Step-by-step explanation:

When the object hit the ground, the distance from it to the ground (or height) will be 0.

Thus,

if when the object touch the ground is when h = 0 then h(t) = 0

So we can set up this equation :

0 = -16t + 100

-100 = - 16t

-100/-16= 25/4 = t
