How would I solve this problem?

  1. Oct 20, 2012 #1
    If I throw an object of mass m with a velocity v against another object of mass M and is stationary, how far would the second object move? Can you please show me how I would solve this? Just show me how to derive the distance it travels, algebraicaly.

    well you know about the conservation of momentum, and I assume the floor has friction. Use these ideas to solve how far it goes

    Yeah using conservation of momentum I can always find the velocity the object will travel but how will I find how far. Ignore friction.

    well if there's no friction on the floor, what is stopping it?

    You would need to know the amount of friction and coefficient of restitution of the collision.

    Jeez I didn't think of that. What an idiot I am. Sorry
