An airplane flies horizontally at a speed of 369 km/h and drops a crate that falls to the horizontal ground below. Neglect air resistance.  A. If the altitude of the plane was 628 m, then how far, horizontally in meters, did the crate move as it fell to the ground?  B. What was the speed of the crate, in m/s, just before it hit the ground?

A marble rolls horizontally off a table that is 0.8 m tall. If the marble lands 0.6 m from the base of the table. a) Draw a sketch of the scenario. b) Determine the time it took for the marble to land. Round to the nearest tenth. c) Determine the initial velocity of the marble in m/s?

4. A ball is shot from a cannon at 50 m/s at an angle of 30° above the horizontal. a. Draw a labeled diagram with all relevant information. Note directions you chose to be +x and +y. b. How far has the ball traveled horizontally when it reaches its highest point in the flight? How high is it at this point? c. What is the speed of the ball at the highest point in its flight?
