If an object is projected upward from ground level with an initial velocity of 48ft per sec, then its height in feet after t seconds is given by s(t)= -16t^2+48t. Find the number of seconds it will take to reach its maximum height. What is this maximum height? The object will take __ second(s) to reach its maximum height. (Simplify your answer.) The maximum height reached by the object is __ feet. (Simplify your answer.)

t = 1.5 s and s(t) = 36 feet

Step-by-step explanation:

The height reached by an object as a function of time t is given by :

...(1)

t is in seconds

To find the maximum height, put

It will take 1.5 seconds to reach its maximum height.

Put t = 1.5 s in equation (1), such that,

The maximum height reached by the object is 36 feet.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

answer: procent 54 wynosi 33,33%
