Homework Help: physics

Posted by emmie on Tuesday, May 8, 2012 at 1:20pm.

A 75kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28 degree incline. After sliding down the 110m long incline (on which the coefficient of kinetic friction is = Bk0.18), the snowboarder has attained a velocity v . The snowboarder then slides along a flat surface (on which Bk= 0.15) and comes to rest after a distance x .

Part a) Use Newton's second law to find the snowboarder's acceleration while on the incline and while on the flat surface.

part b)Then use these accelerations to determine x .
