You are trying to climb a castle wall so, from the ground, you throw a hook with a rope attached to it at 25.6 m/s at an angle of 56.0° above the horizontal. If it hits the top of the wall at a speed of 15.3 m/s, how high is the wall?

  1. Vo = 25.6m/s[56o].
    Yo = 25.6*sin56 = 21.22 m/s.

    Y^2 = Yo^2 + 2g*h.
    (15.3)^2 = (21.22)^2 - 19.6h, h = ?.
