Jack and Linda are arguing about a merry-go-round that was traveling at a constant speed. Jack said that the merry-go-round was still accelerating. Linda said that it was traveling at a constant speed but changing velocity. Who is correct and why?
Linda, because velocity includes direction.
Jack, because acceleration includes direction.
Both Linda and Jack, because both velocity and acceleration include direction.
Neither Linda or Jack, because neither velocity nor acceleration include direction.
