1.38 You lay a rectangular board on the horizontal floor and then tilt the board about one edge until it slopes at angle 0 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 O so that it slides across the board with initial velocity (vox, Voy, 0). Write down Newton's second law using the given coordinates and then find how long the puck takes to return to the floor level and how far it is from O when it does so.

Question
1.38 You lay a rectangular board on the horizontal floor and then tilt the board about one edge until it slopes at
angle 0 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 O so that it slides across the board with initial velocity (vox, voy, 0).
Write down Newton's second law using the given coordinates and then find how long the puck takes to return to
the floor level and how far it is from O when it does so.
