A car moves at a rate of 100 meters per second heading north. If it changes only its direction, what must change?
OA) only its speed
OB) only its velocity
OC) both its speed and its velocity

really your just stupid if you don't know this

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
