To demonstrate this, find the final speed and the time taken for a skier who skies 625 m along a slope that is 28 degrees measured from borizontal, in the following situations (you may neglect friction). Find the final speed (in m/s) of the skier starting from rest. How long (in s) does it take for the skier to reach the bottom of this hill starting from rest? Find the final speed (in m/s) of the skier starting with a speed of 2.50 m/s. How long (in s) does it take for the skier to reach the bottom of this hill with a starting speed of 2.50 m/s?
