Adding Collinear Forces
Adding Collinear Forces
Vectors that are parallel are collinear, even if they have opposite directions.
Two people are dragging a canoe out of a lake onto a beach using light ropes. Each person applies a force of 60.0 N [forward] on the rope. The force of friction exerted by the beach on the canoe is 85.0 N [backward]. Starting with a free-body diagram, calculate the net force on the canoe.
