A 155 m long ramp is to be built for a ski jump. If a skier starting from rest at the top is to have a speed no faster than 23 m/s at the bottom, what should be the maximum angle of inclination?

  • physics -

    f=final o=original

    vf^2=vo^2+2a(delta x)
    23^2=0+2(9.8)delta x
    delta x=27.0,m
    then it's just a trig problem
    sine angle=27.0/155
    angle=10.0 degs.
