I'm pretty sure it needs to be solved through row echelon, but I've tried multiple times and can't seem to work this thing out..can anyone help me?
Problem:
Find the position equation for s=(1/2)at^2+vt+so
At t=1 second, s=128 feet
At t=2 seconds, s=80 ft.
At t=3 seconds, s=0 ft.
Please and thank you if anyone helps! :x
