1. The problem statement, all variables and given/known data A child wants to go ride on her sleigh, and she decides to walk up the Big Hill, of height 100 m relative to where she starts. There are two ways up; the steep way, where the slope is 30.0 degrees, and the not-so steep way, where the slope is 15.0 degrees. The coefficient of kinetic friction between snow and sleigh is fs k = 0,100. The mass of the sleigh is 8.00 kg, the mass of the child is 30.0kg. a) How much work does the child have to do on the sleigh to get it to the top of the hill: the steep way? The not-so-steep way? How much potential energy does the sleigh now have relative to the starting point? b) The child now sits down on the sleigh and slides down the steep side. What is her speed as she gets to the bottom of the hill? What if she would have gone down the not-so-steep side? c) Assuming that after reaching the bottom, she can continue on a horizontal surface of snow, how far does she slide before coming to a halt (steep and not-so-steep)? 3. The attempt at a solution a) In problem a i got The amount of work done on the sleigh the steep way = 2425 J The amount of work done on the sleigh the not steep way = 10813 J Potential energy=7840 J b) Speed down steep side= 40,3 m/s Speed down not steep side= 35 m/s c) I havent solved c yet. All answers are appreciated!
