Hi, What types of mathematical calculations are involoved in designing a spacesuit? Thanks.

I am so not a math buff. I do not even have my grade 11U Math. I am wokring through my math this semester. hehe. So, I have, in this physics course, come inot some difficulties. You know? Is the equation of motion for a mass attached to a spring Fx = kx?

:-p :approve: :smile: o:) :-p :confused: :zzz: :eek: :bugeye: :redface: :cry: :cool: I am getting my grade 12 right now. I am taking my University level Physics, Chemistry, Biology, and English. I am not a math buff, so that means that I will be taking College level Math, which also means, I...

How can I prove that the maximum speed (Vmax) of a mass on a spring is given by 2(pi)fA? Where: f= frequency A= amplitude pi= pi (3.14) How can I do this? :rolleyes:

This is a really good thread. I did enjoy reading this. Thanks to everyone who contributed to this, and the thread starter.

Hahaha. You know what? I figured it out like right after I posted this. Thanks. Everything is fine now:)

A little confused... [FONT="Franklin Gothic Medium"] Allright, I am doing Grade 12 University Prep. Physics, and I am almost finished the 4th Lesson. But I hit this one question and I am little stumped, my teacher does not com in for 15 minutes or so, so I thought maybe you guys would like to...

Time is a creation of man.

Allright:) 1. What's the normal force? Is the normal force the cos of 45(deg) x 9.8? haha. I have no idea? 3. What's the direction of the friction force? The friction force opposes motion of the applied force? So the friction force is acting downwards (parallel to the ramp). And...

Allright so, we will go through it together? (1) What's the normal force? The normal force is the force of gravity 9.8m/s^2 x mass Since I do not know mass, it is 9.8m/s^2m (2) What forces act on the box parallel to the ramp, including the applied force? The forces that act...

So I drew a diagram and I am come up with the idea of needing touse the cosine. As in Cos45(deg)=Fn/9.8, which in turn gave me the force, and in turn I was able to use the Fs=(mu(s))Fn formula. Whatcha think? But I am still kind of stuck on the other one (b).

This is what I have and I have a feeling that I do not understand. 11. A box with a mass of 22 kg is at rest on a ramp inclined at 45 (degrees) to the horizontal. The coefficients of friction between the box and the ramp are: (mu(s): o.78 and mu(k): o.65) a) Determine the magnitude of the...

I just started with my Grade 12 Physics (Univeristy Level), and I would like some help (not necessarily an answer) but an explanation. Here it is: A small box is resting on a larger box, which in turn sits on a table. When a horizontal force is applied to the larger box, both boxes...
