The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal tabletop. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r."Consider the following distinct forces:A downward force of gravity.A force exerted by the channel pointing from q to O.A force in the direction of motion.A force pointing from O to q. Which of the above forces is (are) acting on the ball when it is within the frictionlesschannel at position "q"? The diagram illustrates a circular arc centered around point \(O\), resembling a portion of a circle. Three labeled points—\(P\), \(Q\), and \(R\)—are positioned along this arc. Each point is marked with a circle containing an "X" and a dot, likely indicating a vector pointing into the plane (commonly used to denote magnetic field or current direction, where the "X" represents the tail of an arrow).A counter-clockwise arrow is positioned near point \(P\), suggesting the direction of motion or flow along the arc. The arc is open-ended, not forming a complete circle, and the lines from the points appear to be tangential to the circular path, indicating potential flow directions or forces at play.This diagram can serve as a model to explain various physical phenomena, such as magnetic field direction, current flow in a wire, or forces acting in a circular motion context. Understanding each symbol's meaning in relation to vector direction is critical for interpreting the diagram accurately in an educational setting.

The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. In a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. The toothpick mass was 0.14 g, its speed before entering the branch was 221 m/s, and its penetration depth was 17 mm. If its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick?
