Abicycle and rider travel along a road. which of the following statements is true? a. only the bicycle rider undergoes a translation.
b. the bicycle wheels rotate and translate the entire bike and the rider
c. only the bicycle undergoes a translation.
d. neither the bicycle nor the rider undergoes a translation.

Answer;

The bicycle wheels rotate and translate the entire bike and the rider.

Explanation;

-Body segment rotations combine to produce linear motion of the whole body or of a specific point on a body segment or implement.

-Joint rotations create forces on the pedals. Forces on pedals rotate crank which rotates gears which rotate wheels. Rotation of wheels result in linear motion of the bicyclist and his bike.Bicycle odometers measure linear distance traveled per wheel rotation for a point on the outer edge of the tire.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
