A thin rod extends from x=0x=0 to x=lx=l. It carries a nonuniform mass per unit length μ=mxa/l1 aμ=mxa/l1 a, where mm is a constant with units of mass, and aa is a non-negative dimensionless constant.

Prompta snowboarder stands at the top of a hill and decides to see if he can increase his speed on his next trip down the slope. describe one thing the snowboarder could do to incrlase his speed on the slope. explain why this would cause his speed toincrease relate one of newton's laws to this problem.
