An object is thrown upward at a speed of 175 feet per second by a machine from a height of 12 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2 + 175t + 12. When will the height be 304 feet? When will the object reach the ground?

An object is thrown upward at a speed of 184 feet per second by a machine from a height of 3 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2 + 184t + 3. When will the height be 471 feet? Select an answer: seconds When will the object reach the ground? Select an answer: seconds
