<span>The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.</span>
Given what we know, the type of motion that best describes the trajectory of the athlete and chair along the track is linear motion.
<h3>What is linear motion?</h3>
Linear motion is a type of motion that describes the movement of objects in a straight line. Depending on the exact design of the track this can be subcategorized as rectilinear motion or curvilinear motion. The latter being the case if the track contains a curve.
Therefore, given the motion produced by the athlete and the wheelchair, we can describe it as linear motion, and subcategorize it depending on the exact description of the track.

It is very interesting step about Relative velocity. Actually, when you'll see the speed of fly in relation to ground, then it's speed would be 65 mph as train is traveling by that speed but if a person in on Train, then fly is at rest for him
Hope this helps!
