You and mae are in free-float frames. mae has just passed you, traveling at a speed of 60 km/hr. you throw a ball toward her at a speed of 60 km/hr. what will mae see the ball doing?

Mae will see the ball remaining still in air

Explanation:

In this problem, we have:

- Mae has just passed you, and she is travelling at a velocity of in your reference system

- You throw a ball toward Mae, with a velocity of in your reference system

To find the velocity of the ball in Mae's reference system, we can do

where

v' is the velocity at which Mae's reference system is moving relative to you (which is +60 km/h). Therefore, we have

So, the velocity of the ball in Mae's reference system will be zero.
