You lay a rectangular board on the horizontal floor and then tilt the board about one edge until it slopes at an angle θ with the horizontal. choose your origin at one of the two corners that touch the floor, the x axis pointing along the bottom edge of the board, the y axis pointing up the slope, and the z axis normal to the board. you now kick a frictionless puck that is resting at the origin so that it slides across the board with initial velocity v0 = v0x xˆ + v0 y yˆ . write down newton’s second law using the given coordinate system and use it to calculate how far the puck is from the origin when it returns to floor level.
