1. An object is dropped from a height of 100 m at the same time that a similar object is fired horizontally from the same height. Disregarding the effects of the atmosphere, do they hit at the same time? WHY? 2. Describe the horizontal and vertical velocity and acceleration components of a projectile fired horizontally from the top of a building.

3. Suppose that an airplane flying 60 m/s, at a height of 300m, dropped a sack of flour. How far from the point of release would the sack have traveled when it struck the ground? (Hint: Find the time it takes to hit the ground first)

4. A book is pushed with an initial horizontal velocity of 5.0 m/s off the top of a desk. What is the initial vertical velocity of the book?

5. A ball is thrown horizontally from the top of a building with an initial velocity of 15 m/s. At the same instant, a second ball is dropped from the top of the building. The two balls have the same:

1. paths they fall
2. final velocity as they reach the ground
3. initial horizontal velocity
4. initial vertical velocity
