Find her speed at the bottom of the slope

Reference no: EM13997637

A snowboarder descends from rest straight down a slope with a 20 degree pitch that is 800m long. Her snowboard has a coefficient of kinetic friction of 0.29.

A) if you neglect air resistance, find her speed at the bottom of the slope.

B) if air resistance were included, would a heavier or lighter board reach the bottom first?
