I played enough korean games to know that 50% + 50% doesn't equal to 100%

as a dumb person, i dont think a relative will throw light at me as fast as a ball.

who needs math when you can try every answer untill you get the correct one.

This post has unironically led me down a rabbit hole of relativistic physics, and I'm very grateful for it. Thanks Dapz

But the guys arm is really strong i doubt he wouldnt accidentally throw it too fast and break the light barrier

Similiar to this: If you are stationary and a spaceship has 99% the speed of light inside a system thats going 99% the speed of light inside a system thats going 99%... You only see it moving 99.9999...% the speed of light.

for the extremely cultured Asians out there: if rice bowl flying past you at half speed of light and man trow rice while riding in bowl while gowing speed of light, how fast is rice

Half the speed of light is the initial velocity, so that can't be the answer. Also an object with mass can't equal or exceed the speed of light. You are left with only 1 possible option

For the people wondering: it’s a common problem in physics, relative rates. This is for any scalar quantity. Take two vectors of different magnitude (in this case speed) and run them in the same direction. If the first vector is going half the speed of light (for simplicity’s sake let’s call it 100000 mph). From the perspective of this guy, the speed of light (which is 200000 mph in this example) is only 100000 mph faster than him. If this guy throws something at half the speed of light he’s throwing it at 50000 mph. So since these are in the same direction you just simply add them to get 150000 mph which is .75 the speed of light. Ig the extra 5% in this case comes from his strong arm 😅

i have absolutely no idea but i'm pretty sure i'll get severely injured if it hits me

As a bio student forced to study basic physics. Idk much abt relativity but pretty sure it's not the first two. I guessed 0.75x instead of 0.8x coz if dude is moving half the speed of light then relative to him light is 0.5x more faster than him so if he throw the ball with half the speed of that it shud be 0.25x and adding it to his current 0.5x speed it shud be 0.75x. I am just guessing around

Nothing with mass flies faster than the speed of light or equals to the speed of light

as someone studying special rel in school rn, thanks for the practice question

Imagine a spaceship flies past you at half the speed of light (relative to you).
Then a guy riding that spaceship throws a ball at half the speed of light (relative to him) in the same direction. How fast is the ball traveling relative to you?
(he has a very strong arm)
