+==== Kick Off Questions ====
+  - An object is at rest on a flat, rough, horizontal surface. Compare the horizontal force needed to move the object to the horizontal force needed to keep the object moving with constant velocity once the object is moving.
+  - Consider an object placed on an incline. The inline is a flat, rough surface and is inclined at an angle of $\theta$ relative to the horizontal. Draw a free body diagram showing all forces acting on this object.
+  - In the previous question, what is the angle between the normal(perpendicular) to the incline and the gravitational force?

-Your team has navigated to the bottom of the cliff successfully but are confronted by an incline followed by a tunnel that then leads to the dimensional gate that you might be able to use to get back home. Your amazing piece of tech (turning out to be very useful) indicates that the dimensional gate is at the end of the tunnel and must be entered at a speed of 20mph. It also indicates the angle and height of the incline and the length of the tunnel as displayed in the following screenshot from your tech. The tech also indicates that the base of the tunnel is made of a different surface than that of the incline. Your tech indicates that the incline is made of Leannium and you have conducted previous tests on this material that indicate that a sled can rest on an incline of the material without sliding as long as the angle of the incline is less than or equal to 14º. At the top of the incline are two sleds. You also still have your trusty stopwatch.  You have one chance of escape, for all of your group members to push the sled down the incline and get in, move through the tunnel, and then the dimensional gate. You additionally want to bring back information about the frictional properties of these materials. Will you be successful?
