I checked Marcel's homework from Friday and other than a few minor errors, the work was very good. I told him that his work rated a 100% due to the difficulty level and his effort. We then worked through an example of how horizontal and vertical motion are independent of each other and the calculations involved in projectile motion when an object is launched horizontally and falls vertically. We did four problems and I decided that our progress warranted moving on to projectile motion of objects launched at an angle. I worked through an example of that type of motion and then we ended the session. There was no assignment.
