2. A ball is thrown from a building at an angle of 45 degrees below the horizontal. Immediately after the ball     is released, is the magnitude of its acceleration greater than, less than, or equal to g? Explain?
    The magnitude of its acceleration is equal to g. As the only force acting on the ball is the force due to             gravity.

3. A tank that is traveling at a constant velocity on a level grass field and fires straight up.

5. A drunk driver drives a truck off a cliff 10 meters high. His speed was 20.0 m/s. How far does the truck         land from the base of the cliff?
