use the function s(t)=-16t^2+vt+s for free-falling objects. suppose that an object is released from rest from a height of 1250ft.

a) determine the position function for the object

b) determine the velocity funstion for the object

c) compute the average velocity on the time (seconds) interval [5,6]

d) find the time (in seconds) required for the object to reach ground level

e) find the velocity of the object at impact
