Magnitude & Direction

  1. Nov 25, 2008 #1
    1. The problem statement, all variables and given/known data

    An animal-rescue plane flying due east at 36.0 m/s drops a bale of hay from an altitude of h = 52.8 m, as shown below. If the bale of hay weighs F = 161 N, what is the momentum of the bale the moment before it strikes the ground? Give both magnitude and direction.

    2. Relevant equations
    momentum = mass * velocity
    Newtons = Kg m/s


    3. The attempt at a solution
    how would I converted 161 N to Kg m/s to simply solve mass * velocity?

    I think if you change around the weight formula you should be able to find the mass. W= mass x gravity. Therefore, if you change the equation to be mass = weight/gravity, you should be able to find it.
