In a downhill ski race, surprisingly, little advantage is gained by getting a running start. (This is because the initial kinetic energy is small compared with the gain in gravitational potential energy even on small hills.) To demonstrate this, find the final speed in m/s and the time taken in seconds for a skier who skies 69.0 m along a 25 slope neglecting friction for the following two cases. (Enter the final speeds to at least one decimal place.)
A. starting from rest
Final Speed - ? m/s
TIme Taken - ? s
B.
starting with an initial speed of 2.80 m/s
Final Speed - ? m/s
Time Taken - ? s
