Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

100%

Power
As shown in the picture below, you and a friend are pushing a box horizontally. You
can assume that you and your friend are both pushing completely horizontally in this
case.
Your combined push force (from you and your friend) is Push = 46.0 N. The box has
a mass of 20.0 kg. You and your friend push the box a horizontal distance of 6.50
m. There is a force of friction between the ground and the box with a value of f =
28.0 N. Assume that initially the box is at rest when you and your friend start
pushing it.
What is the rate at which all of the forces do work on the box? This is another way
of asking about Power.
You'll need acceleration to find the time - but you have enough information to
calculate the acceleration.
