1.A child stands 9 meters from the base of the flagpole, which is 10 meters tall. Determine the magnitude of the displacement of the top of the pole with respect to the child's feet.

2.The space shuttle releases a space telescope into orbit around the earth. The telescope goes from being stationary to traveling at a speed of 1700 m/s in 25 seconds. What is the acceleration of the satellite?

3. convert the following
16 cm = ?mm
5.6 m = ? cm

4. Suppose you wish to accelerate a 1200 kg Toyota from 10 m/s to 50 m/s in 10 minutes. What force would you require?

5. A 15kg bullet moving at 300 m/s passes through a 2.0 cm thick sheet of foam and emerges with a speed of 90 m/s. Assuming that the speed change takes place uniformly, what average force impeded the bullet's motion through the plastic?
