Oh, yeah! That's right! They are just equal and opposite...
Do you mean that box 2 has a velocity of 0 at t=0 and it therefore because of the friction will accelerate in the same direction as the velocity of box 1?
I understand that it is a bit confusing when referred to as both box 1 and...
Homework Statement
A small box (mass m1) is placed upon a large box (mass m2); the large box i placed on a horizontal table. The boxes begin a rest on the table. The lower box is hit by a horizontal blow at the time t=0 resulting in a initial velocity v0. The frictioncoefficient between all...
