help me pleaseeeee

Question

A flare is launched from the deck of a lifeboat 8 ft above the water surface. The initial upward velocity is 120 feet per second.

(Vertical Motion Model: h(t) = -16t2 + vt + s)

Write a vertical motion model for this situation

Answer 1

Hi Christina,

h(t) = -16t^2 + 120t + 8

the velocity is feet per second 120 and the height from which is it launched is 8 feet

Answer 2

In this model v is the upward velocity(120) and s is the starting position above the surface (8) so equation is

h(t) = -16t^2 +120t +8
