Answer:
48
Explanation:
It is given in the question that height of an object from his starting point as a function of time of travel in seconds of the object.
If height is given by h and time of travel is given by r seconds, then the height is given by
h = - 16r² + 32r + 48
Therefore, h after 2 seconds is - 16 (2)² + 32 (2) + 48 = 48.
Since height is positive so, we can conclude that after 2 secs the object will be 48 height above the initial position. (Answer)
