CCSS REASONING 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 = 125 - 167-, 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?
