Momentum of particles

  1. Dec 23, 2011 #1
    1)Two objects are at rest on a frictionless surface. Object 1 has a greater mass than object 2. When a constant force is applied to object1, it accelerates trough distance d. The force is removed from object 1 and is applied to object 2. At the moment when object 2 has accelerated trough the same distance d, which statements are true?
    a)P1<p2 b)p1=p2 c)p1>p2 d)K1<K2 e)K1=K2 f) K1>K2

    2) Two objects are at rest on a frictionless surface. Object 1 has a greater mass then object 2. When a force is applied to object 1, it accelerates for a time interval Δt, which statements are true?
    a)P1<p2 b)p1=p2 c)p1>p2 d)K1<K2 e)K1=K2 f) K1>K2


    I need explication too.

    You should try to answer the questions yourself first. You could probably just use intuition, but to be more rigorous, you can use the equations of classical mechanics. Have a go.
