Skier down a hill- f=ma (is the QUESTION correct?)
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...- VidsEpic

Maximum tension between train cars, F=ma
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...- VidsEpic

Skater pulling another skater with a rope, F=ma
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...- VidsEpic

Skater pulling another skater with a rope, F=ma
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...- VidsEpic

How Do Newton's Third Law and Force Calculations Apply to Hockey Players on Ice?
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?- VidsEpic
