Problem 9. A box has an initial speed of 10 m/s. It slides across a flat section and then up an incline. Use L = 20 m, Hk = 0.1

and 0 = 40°. Note that I have not given you the mass. It will cancel out of all the equations in the end! (a) Determine the speed of the box at the end of the flat section. (b) Determine the distance D it slides up the incline before coming to a complete stop.You should be solving/explaining the answer to this using the Work Energy Theorem.
