A large crate with mass mm rests on a horizontal floor. The static and kinetic coefficients of friction between the crate and the floor are μsμs and μkμk, respectively. A woman pushes downward on the crate at an angle θθ below the horizontal with a force F⃗ F→. 1. What is the magnitude of the force vector F⃗ F→ required to keep the crate moving at constant velocity? Express your answer in terms of mmm, ggg, θθ, and μkμk.

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?”
