+225 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^2, 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 rover to return to the ground?
