d. Using your knowledge of the kinematic equations, determine an expression for the object's speed at the bottom of the hill. This should be in terms of some of all of given known variables m, h, L, g, 0 and uk. e. Suppose a snowboarder slides down a ski slope of height h = 12.0 m, length L= 100 m and the coefficient of kinetic friction between their board and the snow is Hik= 0.07. What is the snowboarder's speed at the bottom of the hill? Suppose this snowboarder has a little sister who is half the mass of her older sibling. What is the little sister's speed at the bottom of the hill? Does your result make sense? Explain.
