Santa loses his footing and slides down a frictionless, snowy roof that is tilted at an angle of 45°. If Santa slides 6 m before reaching the edge, what is his speed as he leaves the roof?
I am having trouble getting started because I am not sure what equation to use (it seems like I probably need something to do with sin/cos/tan, but I am not that great at geometry). Any help on how to get started would be great.

Vertical distance he "falls" = (sin 45) x 6, = 4.243m.
Velocity after 4.243m. = sqrt. (2ad), = sqrt. (19.6 x 4.243) = 9.12m/sec.

I'm not an expert,but I think you will have to use weight multiplied by cos 45
nevertheless I think there's something missing
