An object is thrown upward at a speed of 60 feet per second by a machine from a height of 13 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2 + 60t + 13. When will the height be 52 feet? When will the object reach the ground?

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?

The height $h(t)$ in feet of an object $t$ seconds after it is propelled straight up from the ground with an initial velocity of 85 feet per second is modeled by the equation $h(t)=-16 t^{2}+85 t$. Will the object ever reach a height of 120 feet? Explain your reasoning.
