The coefficient of kinetic friction between a 22kg crate and the floor is .3. what horizontal force

If the coefficient of kinetic friction between a 22kg crate and the floor is 0.30. what horizontal force is required to move the crate at a steady speed across the floor? What horizontal force is required if uk is zero? .

I subscribed! please make more videos, you are a life savier, and are so good at explaining! you make it sound easy, and your voice is soothing.
Thank you.

Amazing way better than my teacher thank u

Thanks this a big help for our modules

Please I don't understand why the first question is equal to fk because the horizontal force required for the body to move must be greater than fk

l have a question, what if the coefficient of kinetic friction, between a crate and a horizontal floor is 0.27 . if the crate has a mas of 250-kg, what force is needed to slide it across the floor at constant velocity? then what will be the answer?

Please, how can I get the acceleration of the object when it stops moving?

i have a question how did u get 9.8 when u multiplied the mass with gravity (also awesome video) im trying to do a physics home test but i dont quite get this part
