ok, a 90kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant speed. find mu s and mu k between the clock and the floor.

Any help at all is appreciated. thanks!

My sisters math problem, it says "evaluate the expression", and thats it, which means simplify were guessing.

1. 27 4/3
she started to evaluate it, and has
27 to the third power inside of the square root symbol,
with a three over top of the check part.
Please help! I'm gussing that the teacher wants you to simplify it using sqare roots, obviously.

Thanks!
