Homework Statement
consider a ski jumper moving down a track to acquire sufficient speed to accomplish the ski jumping task. The length of the track is L=25m and the track makes an angle of 45° with the horizontal
if the skier starts at the top of the track with zero initial speed , determine the take off speed of the skier at the bottom of the track using
i) the work-energy theorem
ii) the conservation of energy principle
iii) the equation of motion along with kinematic relationships
assume that the effects of friction and air resistance are negligible
i have no idea how to even start this problem so any help would be greatly appreciated
