Rhea kicks a soccer ball at 13 km/h to sean. after kicking the ball, the speed of the soccer ball from rhea’s reference frame is 13 km/h. the speed of the soccer ball from sean’s reference frame is 22 km/h.
which conclusion is best supported by the information?
a. rhea is standing still after kicking the ball, and sean is running.
b. sean is standing still, and rhea is running while kicking the ball.
c. both soccer players are standing still after the ball is kicked.
d. both soccer players are running while the ball is in motion.
