Question 434419: Need help setting up this equation. If an object is projected vertically upward from an altitude of s0 feet with an initial velocity of v0 ft/sec, then its distance s(t) above the ground after t seconds is
s(t) = −16t2 + v0t + s0.If s(1) = 79 and s(4) = 64, what are v0 and s0?

\ =\ -16t^2\ +\ v_ot\ +\ s_o)
\ =\ -16(1)^2\ +\ v_o(1)\ +\ s_o\ =\ 79)
\ =\ -16(4)^2\ +\ v_o(4)\ +\ s_o\ =\ 64)
Just solve the 2X2 system.

My calculator said it, I believe it, that settles it
