Homework Help: Projectile motion of a rabbit

  1. Jan 8, 2009 #1
    When chasing a hare along a flat stretch of land, a greyhound leaps into the air at a speed of 9.9 m/s, at an angle 27 degrees above the horizontal

    Vf= Viy + at
    displacement= Vyt + .5at squared

    0= 4.95 (y component for velocity) + 9.81t
    t= .504
    y= 4.95x.504 + .5x9.81x.504 squared
    y displacement= 3.78

    using tan 27= 3.745/x
    x displacement= 7.33

    multiplied by 2 = 14.66
