We seem to be doing the same homework! http://www.lakeheadschools.ca/scvi_staff/childs/Gr11_physics_web/downloadable_content/unit3/textpdf3/phys11_3_5.pdf

3rd time I'm posting in a day. Homework Statement A skier (68 kg) starts from rest but then begins to move downhill with a net force of 92 N for 8.2 s. The hill levels out for 3.5 s. On this part of the hill, the net force on the skier is 22 N [backwards]. T/I (a) Calculate the...

Homework Statement A locomotive (6.4 × 10^5 kg) is used to pull two railway cars (Figure 11). Railway car 1 (5.0 × 10^5 kg) is attached to railway car 2 (3.6 × 10^ kg) by a locking mechanism. A railway engineer tests the mechanism and estimates that it can only withstand 2.0 × 10^5 N of...

If you look at the other questions, you will find some very vague and strange questions. I encounter a lot of irregular patterns. For example sometimes they ask for a force, and I am not sure whether they want the net force, or the applied or the tension, and in the answer key, I actually figure...

So that was it! Thanks a lot!

Homework Statement Two people, each with a mass of 70 kg, are wearing inline skates and are holding opposite ends of a 15 m rope. One person pulls forward on the rope by moving hand over hand and gradually reeling in more of the rope. In doing so, he exerts a force of 35 N [backwards] on...

The diagram looks like this:http://i.imgur.com/LP6NfNw.jpgsome people are telling me that it is 10N left on the 100kg object? Is it correct that I consider on each object the force of its own reaction + the force applied to it so that on 100kg I have 90N left and on 112kg I have 90N right?

Is this correct?

Homework Statement two hockey players are standing on ice. Player A is 100kg and player B is 112kg, Player A pushes B with 40N and player B pushes A with 50N. what are the action/reaction forces? what are the accelerations?Homework Equations F = maThe Attempt at a Solution player A has a...
