Video: Boy on a Surfboard In the video below, Siri and Carl are doing a physics experiment because their father asked them to. Carl stands on an old windsurf board while his sister Siri (who has become chilled in the late summer afternoon) holds the board in place. Siri releases the board and Carl walks toward the front of the board and then back to his original position. Important note: Siri and Carl took turns walking on the board and holding the board until we recorded one shot that worked perfectly. By chance, it was Carl walking on the board during that shot. Siri was not relegated to holding the board every shot. 1. Let's explore the motion of the Carl and the board. Use the ruler tool and the video to answer the following questions.

Describe some possible reasons for the discrepancy between your answer from the previous section and the actual value. ) Hint: As always, 'human error' is not an acceptable response. Score: 0/5S 4. Let's analyze this system using the formal definition of center of mass for a two-particle system: T com (mizi+m212) (m1 +m2 Let's assume that the external forces on the system (Carl and the board) are negligible (small enough to be ignored). Make measurements from the video and use them to determine the mass of the board. Hint: . Carl's mass is 33.3 kg . The center of mass of a human standing straight up is located between their belly-button and spine. . The center of mass of the board is the black plastic insert that is directly in front of Siri before Carl moves
