Tad drops a cherry pit out the car window 1.0 m above the ground while traveling down the road at 18 m/s. If the car continues to travel at the same speed, where will the window be in relation to the pit when it lands?

• Right above the pit still.

• Behind the pit.

• In front of the pit.

While skiing, Ellen encounters an unexpected icy bump, which she leaves horizontally at 12 m/s. How far out, horizontally, from her starting point will Ellen land if she drops a distance of 7.2 m in the fall?

The Essex county sheriff is trying to determine the speed of a car that slid off a small bridge on a snowy New England night and landed in a snow pile 4.05 m below the level of the road. The tire tracks in the snow show that the car landed 27 m measured horizontally from the bridge. How fast was the car going when it left the road?

The movie The Gods Must Be Crazy begins with a pilot dropping a bottle out of an airplane. It is recovered by a surprised native below, who thinks it is a message from the gods. If the plane from which the bottle was dropped was flying at an altitude of 500 m, and the bottle lands 400 m horizontally from the initial dropping point, how fast was the plane flying when the bottle was released?
