Earth's frame O Bicycle's frame 5 mph 5 mph This sketch shows the speeds relative to the Earth or, as we will often say, "speeds observed from the Earth's reference frame." (We could also say "speeds from my frame" or "speeds from the sidewalk's perspective" or "speeds from the sidewalk's frame" or "speeds in the sidewalk's frame." All of these phrases have the same meaning.) The Paradox of the Mirror But I'm not the only person who can observe this scene. The cyclist is just as good a person as I am. From the point of view of the cyclist, the car is still moving, but it's not drawing away from him as quickly as it's drawing away from me; in fact, it's mov- ing at 15 miles/hour as observed from the bicycle's reference frame. Meanwhile, from the point of view of the cyclist, the home is drawing away from the bicycle. In fact, it is moving left at 5 miles/hour (or, what is the same thing, right at -5 miles/hour). Here's a sketch of the situation from the cyclist's point of view: Ò 20 mph 0 mph 5 15 mph

Expert Solution
Step 1

In given we are asked to find distance travelled by car as observed from different frames.

In order to find the distance we have to find speed of the car relative to the corresponding frame which can be found using relative speed concept.
