How long will it take to reach half of the distance to the ground, 72 feet?ī. The height in feet of an object dropped from the top of a 144-foot building is given by h ( t ) = − 16 t 2 + 144, where t is measured in seconds.Ī. How long does it take the object to hit the ground?ġ01. The height in feet of an object dropped from a 20‑foot platform is given by h ( t ) = − 16 t 2 + 20, where t represents the time in seconds after the object has been dropped. How long does it take the object to hit the ground? (Hint: The height is 0 when the object hits the ground.)ġ00. The height in feet of an object dropped from a 9‑foot ladder is given by h ( t ) = − 16 t 2 + 9, where t represents the time in seconds after the object has been dropped. If the diagonal measures 2 feet, then find the dimensions of the rectangle.ĩ9. The length of a rectangle is 3 times its width. If the diagonal measures 5 meters, then find the dimensions of the rectangle.ĩ8. If the diagonal measures 8 feet, then find the dimensions of the rectangle.ĩ7. The length of a rectangle is twice its width. If the diagonal measures 10 feet, then find the dimensions of the rectangle.ĩ6. The diagonal of a square measures 3 inches.
