**force!! help me please =)**

## Homework Statement

It's moving day and you need to push a 100kg box up a 20 degree ramp into the truck. The coefficients of friction for the box on the ramp are Us=0.9 and Uk=0.6. Your largest pushing force is 1000N. Can you get the box into the truck without assistance if you get a running start at the ramp? If you stop on the ramp, will you be able to get the box moving again?

## Homework Equations

Fk=Ukmg

F=mgsin20

## The Attempt at a Solution

a) Fk=(0.6)(100)(9.8)

=588N

F=mgsin20

=335N

yes, my maximum pushing force is 1000N. 335N<1000N

b) Fs=Usmg

=882N

Yes. I will be able to get the box moving again because I have enough force to overcome the static force.

thank you!!!!!!
