    Force, constant speed, friction, acceleration

    I would really appreciate any help on this. I'm confused with this. Homework Statement An empty crate is sliding witha speed of 7m/s over a frictionless surface when it hits a rough patch where .25 is the coefficient of kinetic friction. Find the distance it takes to stop the box. The...

    How hard must you push a box to move it with a constant speed?

    Homework Statement How hard do you need to push a 2kg box which has .2 coefficient of kinetic friction so that it moves with a constant speed of 5m/s? [The Attempt at a Solution (I'm calling g 10m/s2 not 9.8) F(kinetic friction)=(.2)Fn=(.2)mg=(.2)(20N)=4N so...since the acceleration is...
