8. a 220n box is set on 100 decline. what is the force of friction if the coefficient of static
docsit me
friction is 0.67? does the object slide down, if so, with what acceleration? you may change
these numbers around for practice

9. a 400 n box is on a level floor. instead of pushing it, you decide to drag it
ver floor. instead of pushing it, you decide to drag it by attaching a
rope at a 45°. you are able to muster 200 n of force pulling at that angle. with
