3. A bicyclist traveling at a speed of 8 m/s to the left coasts (stops peddling) along a gravel road such that the bike experiences a frictional force of 24 N. The combined weight of the bicycle and rider is 800 N. (a) Draw a complete force diagram for the rider/bicycle combination, labeling each force and its value. 8m/s Fapp Phom 24N Fr mls 800N (b) What is the value and direction of the net force acting on the bicycle in this scenario? (c) The net force is acting in the (opposite, same) it will cause the bicycle to have a (positive, negative) direction as the motion of the bicycle, so (slow down, speed up) acceleration, so it will

1. A 100-g box slides across a frictionless horizontal plane and is accelerating at 15 m/s2. What is the opposing force needed to reduce the acceleration to 5 m/s2. Note that the question is asking for the opposing force to the original force, NOT the resultant force that results to 5 m/s2.
