A ball is thrown straight up from the top of a 64 foot tall building with an initial speed of 48 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t^{2} + 48t + 64. How long will it take for the ball to hit the ground? |

A ball is thrown straight up from the top of a 112 foot tall building with an initial speed of 96 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t^{2} + 96t + 112. When will the ball reach a height of 240 feet? |

A ball is thrown straight up from the top of a 30 foot tall building with an initial speed of 74 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t^{2} + 74t + 30. How long will it take for the ball to hit the ground? |

A ball is thrown straight up from the top of a 224 foot tall building with an initial speed of 80 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t^{2} + 80t + 224. When will the ball reach a height of 308 feet? |
