I do know that the velocity vector is tangent to the wheel. Here's the image attached.

|dw:1442571304048:dw|

So the angle for velocity vector should be 30 degrees?

You can find the velocity vector using conservation of mechanical energy.

And how do I do that? Could you elaborate a bit?

one min..

m is not given in the question.

Oh okay. So \[80 \pi \cos 30\] is not the correct horizontal velocity component?

That's what i think..

@IrishBoy123 , what do you think?

@emcrazy14
does that make sense to you?
does it need to be broken down?

let me do it ignoring gravity as i think the numbers make no sense
just a sec

Okay, sure.

*already

of course - because gravity has virtually no time to act, which is why the question looks so odd

Okay. Thank you so much. The question is indeed very odd. Really appreciate your help throughout. :)

WoW!!

Thanks irishboy c:
