1. A bicycle is travelling at constant velocity on a horizontal road. Which of the following statements are true? (You may choose more than one.) O a) The total force on the bicycle is parallel to the motion. O b) The total force on the bicycle is antiparallel to the motion. O c) No forces are acting on the bicycle. O d) Various forces are acting on the bicycle, and their sum is zero. O e) Air resistance forces are approximately parallel to the velocity. O f) Air resistance forces are approximately antiparallel to the velocity. O 8) Overall, friction between the tires and the road is pushing the bicycle forwards.
