A ball is lodged in a hole in the floor near the outside edge of a merry-go-round that is turning at constant speed. Which kinematic variable or variables change with time, assuming that the position is measured from an origin at the center of the merry-go-round?

a. the position of the ball only
b. the velocity of the ball only
c. the acceleration of the ball only
d. both the position and velocity of the ball
e. the position and velocity and acceleration of the ball

do the magnitudes of the position, velocity, and acceleration vectors change with time? yes/no?
