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? sean is standing still, and rhea is running toward sean while kicking the ball. rhea is standing still after kicking the ball, and sean is running away from rhea. both soccer players are standing still after the ball is kicked. both soccer players are running while the ball is in motion.

Rhea is standing still after kicking the ball, and Sean is running away from Rhea.

Explanation:

Here the speed of soccer ball in ground frame of reference is 13 km/h

Now it is given that after kicking the ball the speed of is observed by Rhea as 13 km/h while the speed of ball observed by Sean's frame is 22 km/h.

Now here we can say by relative frame of reference we have

so here if ground frame speed is same as the speed in Rhea frame then we can say that Rhea must be at rest or his frame is having same conditions as that of ground.

So here we can say Rhea is standing still after kick the ball.

Now in Sean frame of reference we will say that ball is observed at 22 km/h which is more than the speed of ball in ground frame.

So here the speed is Sean frame will be opposite to the speed of ball so that net speed will be more

So here correct answer will be

Rhea is standing still after kicking the ball, and Sean is running away from Rhea.
