The question is incomplete. It comes with a set of answer choices.
These are the answer choices:
Alex observes it as 10 m/s, and his friend observes it as less than 10 m/s.
Alex observes it as less than 10 m/s, and his friend observes it as 10 m/s.
Both Alex and his friend observe it as 10 m/s.
Both Alex and his friend observe it as less than 10 m/s.
Answer: Both Alex and his friend observe it as 10 m/s.
Justification:
1) The speed is relative to the frame of reference.
2) It is said that the both Alex and his friend are standing still.
3) Then, the speed they both see is the same, 10 m/s, respect the Earth (where they are standing still).
Of course, Alex is watching the ball moving away and his friend is seing it approaching, but it is not relevant for the question, as it deals with the speed which is only about magnitude, not direction.
I think it's 21 that's what I got when I was on that answer
This isn't a physics question really, but you should slow down unless you don't believe you can stop in time or don't believe it is safe to stop quickly (say you see someone driving very close behind you and you don't think they're paying attention). In general, if you think that by staying at your current speed your back tires will cross the ending lines of the intersection by the time the light turns red, it is safe to go through the yellow light. However, this is a thing you'll develop a feel for as you're driving, when in doubt, just slow down, just watch slamming on your breaks if there is someone behind you, sometimes people will see the yellow light when they're behind you and they'll speed up behind you so they'll "make it" before the light turns yellow. While this isn't illegal, since they're not technically running the red light, you should never speed up going up to a yellow light, if you need to speed up to make it before it turns red, you shouldn't make the light, just stop, this is especially bad if someone is directly in front of you and is likely to stop at the yellow light while the person behind them speeds up. This causes a lot of accidents.
