Skier A Skier B m = 70 kg m = 50 kg Two skiers start from the same height on opposite sides of a hill. Skier A has a mass of 70 kg while Skier B has a mass of 50 kg. /.ssume that friction and air resistance are negligible. a. Compare the speeds of the skiers a the bottom of the hill: Greater for Skier A Same speed for both Greater for Skier B Explain b. Compare the kinetic energies of the skiers at the bottom of the hill: Greater for Skier A Same kinetic energy for both Greater for Skier B Explain. c. Compare the times taken to get to the bottom of the hill: Greater for Skier A Same time for both Greater for Skier B Explain
