... Problem 4 (20 points): A diver comes off a board with arms straight up and legs straight down, giving her a moment of inertia about her rotation axis of Ii = 18 kg·m2 . She then tucks into a small ball, decreasing this moment of inertia to If = 3.6 kg·m2 . While tucked, she makes two complete revol ...

... A wad of sticky clay with mass m and velocity vi is fired at a solid cylinder of mass M and radius R. The cylinder is initially at rest, and is mounted on a fixed horizontal axle that runs through its center of mass. The line of motion of the projectile is perpendicular to the axle and at a distanc ...

Newton`s Laws of Motion
... – Either force in an interaction can be the ‘action’ force or the ‘reaction’ force. – Unfortunately we associate ‘action’ and ‘reaction’ with ‘first an action, then a reaction’. • This is NOT what occurs in the third law. The action force and the reaction force exist at the SAME time. ...
