Wanna win 50k credits fast? :)

[25thhour]

I need some physics help...

I have this question that has been pissing me off all day in which I know the friggen answer but I cannot show my work to get it... Please show me the work and I'll send ya 50k credits


The Question:

A man shoots a slingshot at a thief who is 50 meters away. He hears the thief scream 1.5s later. The Speed of sound is 330m/s. What was the initial velocity of the shot object.

The only thing I could figure out to do is 50m/330m/s to get me the actual time to took the projectile to reach the thief.

Thanks! (Yes, I know this a simple question... I suck at physics...)

50m / (1.5 sec - 50/330 sec) ~ 37.08 m/s

50/330 sec is the time the scream takes to travel from the thief to you.

1.5 sec - 50/330 sec is the time the bullet takes to travel from you to the thief.

Blah, I kinda thought I had to subtract the 1.5 from the other time. Durp.

Thanks a ton Creds on the way.

No, Velocity is LOL (currently, but I think he's able to change his credit count?)

Smitty has 3 million I think

Reincarnate had the max when he donated to ichlie's tournament (5 million), 8388607 but that was BS. XD

Question has been answered, so locked.


If you guys want to talk about credit counts you can make a thread about it
