Billy gets onto a big wheel and goes around once (a total of 30m) in one minute.
When he gets off, he tells Tara that his
displacement was zero. Tara reminds him
that he travelled all the way around the
wheel (30m).
Explain how both Billy and Tara are correct.

Are they a thing or something

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
