Okay, so here is what I did:
Total forces of X are Force of friction, force of gravity and force of inertia. I obtained the Normal force by using the the y component of gravity (36 x 9.8(cos10)) and then using that number I obtained the value for the force of friction to be 132.03.
Plugging...
Yes I believe I understand, because the frictional forces are perpendicular to the area of contact? Ahhh, this is always the problems I have with physics! :) Thanks much for the help.

Homework Statement
Anthony is going to drive a flat-bed truck up a hill that makes an angle of 10 degrees wtih respect to the horizontal direction. A 36.0-kg package sits in the back of the truck. The coefficient of static friction between the package and the truck bed is 0.380. What is the...
Okay, so I began by analyzing the total forces of both the astronaut and the asteroid. The total forces on the astronaut = -250N = ma so I then found the acceleration of by dividing -250 by mass 60kg to obtain a=-4.17. Doing the same thing for the asteroid I used a postive 250/mass 40kg and...
So one question before I get going, my professor had said that the total time would be 5.35 and that the wording of the problem is just a bit confusing. Does this sound right? Thanks much for the help!
Homework Statement
An astronaut of mass 60 kg and a small asteroid of mass 40 are initially at rest with respect to the space station. The astronaut pushes the asteroid with a constant force of magnitude 250N for 0.35s. Gravitational forces are negligible. A)How far apart are the astronaut and...
