Okay, a woman exerts a constant horizontal force on a large box.
00:12
There she is pushing it.
00:13
That is a terrible picture.
00:19
Okay, a little bit better.
00:22
She exerts a constant force, and as a result, it moves at a constant speed, v -not.
00:30
Okay, so now if she doubles the force on the same floor, what will happen to the box? okay, let's look at the forces here.
00:40
So initially with the force of f and then we'll look at it with the force of 2f.
00:51
So with a force of 1f, the forces on the box are the applied force by the woman, the frictional force from the ground, the normal force, and the weight.
01:04
And then for our other case, same thing, except 2f now...
