1. A football is kicked from the ground at 15m/s at an angle of 30 degrees above the horizontal. How long does it take for the ball to return to the ground?

2. A ball is kicked with an initial velocity of 7m/s at 55 degrees above the horizontal. It strikes a window that is horizontally 1m from the kicker. How high is the window above the ground?

3.A ball is thrown off of a building in the +x direction at 10m/s. If the ball takes 2s to land, how tall is the building?

4. A person walks 400km in the -x direction and then walks 300km 25 degrees above the +x axis. What is the displacement of the person?

5.Use the component method to find the displacement when a person travels 5m in the +x direction and then 17m in the +y direction.
