To a good approximate, the only external force that does work on a cyclist moving on level ground is the force of air resistance. suppose a cyclist is traveling at 15 km/h on level ground. assume he is using 480 w of metabolic power.
a. estimate the amount of power he uses for forward motion.
b. how much force must he exert to overcome the force of air resistance?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
