Q.1) A ball is shot at high speed into a frictionless channel that is in the shape of a segment
of a circle with center at 0.The channel is frictionless and sits on a horizontal table top.The
figure shown is the top view.
Which of the following force(s) are acting on the ball when it is within the frictionless
channel at position B? Explain your answers.
Check all that apply.
A downward force of gravity.
A force pointing from O to B.
A force in the direction of motion.
A force pointing from B to 0.
Which path would the ball most closely follow after it exits the channel at C and moves
across the frictionless table top?
1. Each of the following free body diagrams represents a different problem. Solve for the missing quantities and then place your answers in the space provided. Don’t forget UNITS and DIRECTIONS! Consider all directions on a compass grid with ↑ as north [N]. please hand write it clearly.
Concurrent forces are forces that act at a single point. The assignment cards show concurrent forces but the forces on the force table act on a ring, not at a point. Nonetheless, the forces are still concurrent. Explain.
