In each case, a rock is acted on by one or more forces. All drawings are in a vertical plane, and friction is negligible
except where noted. Draw accurate free-body diagrams showing all forces acting on the rock. Please use a ruler,

17. Tied to a rope and pulled straight downward.
Accelerating downward at 19.6 m/s. No friction.
18. Tied to a rope and pulled so that the rock moves
horizontally at constant velocity. Note: There must be
air friction in this case.
