1. The problem statement, all variables and given/known data As a participant in a robotic competition, you must launch a potato from a moving cart and strike a target. The potato must reach the apex of flight just as it travels over a screen, then it must pass through the center of an opening in a wall. The cart moves at a steady speed of 20cm/s (+x). The potato is launched from a height of 10 cm above the floor. The screen is 85 cm tall. The center of the opening in the wall is 20cm from the floor. The wall is 125cm to the right of the screen. The situation is diagrammed below (I attached a picture) How far from the screen should the potato be launched in order to make the shot? 2. Relevant equations 3. The attempt at a solution So I used the information from the right side to find time from apex to the opening of the window and that help me find the velocity in the x direction and the angle but I don't know how any of this relates to the cart and now I'm stuck!!
