Homework Statement A worker pushed a 26kg block 13m across a level floor at a constant speed, with a force directed 40 degrees below the horizontal. If the coefficient of kinetic friction between the block and floor is 0.40, what were a.) the work done by the workers force? and b.) the...

Figured it out, thanks!

I'm not sure what you are referring to with "ω". I am also not sure hot to find N, if i do not know the mass of the cat.

Homework Statement A cat sits on a merry go round at a radius of 4.0m from the center. The ride makes one complete rotation every 6.3 seconds. What is the least coefficient of static friction to keep the cat in place? Homework Equations Circumference = 2Pi*r V=d/t a=v^2/r The...
