A ball is thrown straight upward with some initial speed. When it reaches the top of its flight (at a height h), a second ball is thrown straight upward with the same initial speed. Where with the balls cross paths? 1.At height h. 2.Above height h/2. 3.At height h/2. 4.Below height h/2 but above 0 height. 5.At height 0.

You drop a rock off a bridge. When the rock has fallen 4 m, you drop a second rock. As the two rocks continue to fall, what happens to their separation? 60 1.Their separation increases. 2.Their separation stays constant at 4m. 3.Their separation decreases. 4.It is impossible to answer with out more information. 1234567891011121314151617181920 2122232425262728293031323334353637383940 4142434445464748495051525354555657585960 6162636465

You drop a package from a plane flying at constant speed in a straight line. Without air resistance, the package will: 30 1.Quickly lag behind the plane while falling. 2.Remain vertically under the plane while falling. 3.Move ahead of the plane while falling. 4.Not fall at all. 1234567891011121314151617181920 2122232425262728293031323334353637383940 4142434445464748495051525354555657585960 6162636465

A projectile is launched from the ground at an angle of 30 o. At what point in its trajectory does this projectile have the least speed? 30 1.Just after it is launched. 2.At the highest point of its flight. 3.Just before it hits the ground. 4.Halfway between the highest point and ground. 5.The speed is always constant. 1234567891011121314151617181920 2122232425262728293031323334353637383940 4142434445464748495051525354555657585960 6162636465
