I did look at the book. This test is HARD! I figured out most of the questions but still have three more to go.

Help with Angular Momentum! I am trying to figure out these questions and i just don't know. So I thought maybe you could help me. Thanks 1: A bolt on a car engine is to be tightened with a torque of 35 Newton meters. If you have a 25 cm long wrench, what force should you exert? 1.4 N...

Ok. After that what do I do? I am trying to figure out what equations to use!

Practice Problems! Confused on what equations to use! Homework Statement Question 1: Calculate the angle of banking of a curve 200m in radius in order hat traffic moving at 70 km/h may round the curve without depending on friction. Homework Equations Don't know Homework...

How am I supposed to do that? This question is so confusing.

I see how you got that. What do I do next?

Ok.. so the answer would be 245N but the closest one I have is 250N. Thanks!

I understand now what you are saying. I did two weeks on vector math and totally understood it but what does that have to do with this problem. How do I figure out the answer?

F>(mu)k/(mu)s (mu)kmg<=(mu)smg (mu)smg=F The scenario described is physically impossible. This is exactly how they look. I am so confused on this one. Just so you know... this is one scenario not two.

I have done very little with force vectors. This is all new to me. My teacher never really explained it well since I am homeschool by online programs.

So you are saying that the forces need to be equal? So since T2 is at a magnitude of 10N does that mean that the magnitude of T1 is 10N too?

Not really, I don't know what to do. I understand number 1. But how does that make me figure it out.

Homework Statement A person is pushing an object of mass m along the ground with force F. The coefficient of kinetic friction between the object and the ground is (mu)k. The object is accelerating, but then the person stops pushing and the object slides to a halt. The person then starts...

What? I have no idea at all for this. My teacher just said to use trig functions to find the hypo of T1 which will then be the magnitude.

Well I know that the cosine of 30 is correct. Am I not supposed to multiply?
