What is the instantaneous velocity of a freely falling object 28 s after it is released from a position of rest? The acceleration of gravity is 9.8 m/s2 .

2)What is its average velocity during this 28 s interval?

3) How far will it fall during this time?

This is not deep material.

vf=g*t solve

avg= vf/2

h= avgvelocity*time
