At a fourth of july celebration, a rocket is launched straight up
with an initial velocity of 125 feet per second. the height h of the rocket in feet
above sea level is modeled by the formula h = 125t - 16t”, where t is the time in
seconds after the rocket is launched.
a. what is the height of the rocket when it returns to the ground?
b. let h = 0 in the equation and solve for t.
c. how many seconds will it take for the rocket to return to the ground?
