A brick is thrown off a building at a 25 degree angle at 10m/s, it lands 40 meters away, How high is the building?

  • Physics -

    Time of flight = t = (40 m)/(Vo*cos25)
    = 4.41 s
    since the horizontal velocity component is constant.

    Vo*sin25*t - (1/2)gt^2 = -(Height)
    since the vertical location is
    -(Height) when it hits the ground

    Height = 4.9 t^2 - 4.226 t
    = 95.3 - 18.6 = 76.7 m
