Problema Solution
when an object is dropped,its height h can be determined after t seconds by using the falling object model h=-16t2+s where s is the initial height.find the time it takes an object to hit the floor when it is dropped from a height of s feet
Answer provided by our tutors
the object hits the floor when h = 0 after some time t, t>0
that is:
0=-16t^2+s
by solving for t we find:
t = (1/4)√s seconds

it takes (1/4)√s seconds for the object dropped from a height of s feet to hit the floor.
