Santa loses his footing and slides down a frictionless,snowy roof that is tilted at an angle of 27.0.
If Santa slides 9.00 m before reaching the edge,what is his speed as he leaves the roof?
1 answer
he fell exactly 9*sin27 meters in altitude. His speed at the bottom then is vf=sqrt(2*9*sin27*9.8) m/s
