Homework Help: Aceleration force mass question

  1. Nov 18, 2009 #1

    1) The problem statement, all variables and given/known data

    If a cow eating grass (at rest) and having a mass of 408.6 kg slides down a 10 meter slope in 1.5 seconds. What is the net force on the cow?

    2) A net force of 450 N is applied to a .333 kg baseball, what is its acceleration?

    2. Relevant equations

    force = mass * acceleration

    3. The attempt at a solution

    No idea how to do number one! Is number two, 450=.333(acceleration) ?

    remember it's net force=mass*acceleration
    what's the acceleration of the cow using the kinematic equations? Then apply your relevant equation.
    Yes, solve for the acceleration, but don't forget to use the proper units; when the mass is in kg and the force is in N, then the acceleration has the units of_______???
