Question

1. describe you are walking toward the back of a bus that is moving forward with a constant velocity. describe your motion relative to the frame of reference of the bus and relative to the frame of reference of a point on the ground.

Explanation:

In the frame - of - reference of the bus moving forward, since you are walking toward the back of the bus, your motion is backward. In the frame - of - reference of a point on the ground, your motion depends on the relative magnitudes of your walking speed and the bus's speed. If your walking speed is less than the bus's speed, you are still moving forward relative to the ground but at a reduced speed compared to the bus. If your walking speed equals the bus's speed, you are stationary relative to the ground. If your walking speed is greater than the bus's speed, you are moving backward relative to the ground.

Answer:

Relative to the bus, you are moving backward. Relative to a point on the ground, you may be moving forward (at a reduced speed if your walking speed is less than the bus's speed), be stationary (if your walking speed equals the bus's speed), or be moving backward (if your walking speed is greater than the bus's speed).
