A 300kg bobsled starts down an icy slope inclined at 12 degrees. There is some friction between the bobsled and the slope. Write the equations of motion in the two directions where the x axis is along the hillside.

Answer 1

Net force=Mass*acceleration
mgCos12-mg*mu*Sin12=mass*acceleartion

now, knowing acceleration...

vf= acceleration*time
distancedown=1/2 acceleration*time^2
