Ohh I see. As I'm in beginning physics and this is a problem at the start of a new unit, I think the teacher didn't want to confuse us. If I did want to take that into account, how would I go about doing that?

OK, so then I would need to use Conservation of Energy? Potential energy of block -> kinetic energy -> potential energy in spring? mgh = 1/2kx2 x2 = 2mgh/k x = 5.42m Do you mean the GPE of the block when it's resting on the spring?

Homework Statement A 2.0 kg object starting at rest falls 3.0 m onto a 4.0 N/m spring. How far will the spring be compressed? m = 2.0 kg vo = 0 m/s2 y = 3 m k = 4 N/m g = -9/8 m/s2 Homework Equations eq1: Fg = mg eq2: Fspring = -kx The Attempt at a Solution [/B] eq1: Fg = mg Fg =...

LOL. Now every time I say my age, I'll think of you and make sure to add years onto the end.

Oh haha. The charge of an electron is -1.6x10-19 Coulombs therefore the charge of a proton is +1.6x10-19 Coulombs. Thank you :).

Oh, I understand. So because the charge of an electron is -1.6x10-19, the charge of a proton would be +1.610-19? And this charge can be used for q1 and q2.

Homework Statement Two protons in an atomic nucleus are typically separated by a distance of 2x10-15 m. The electric repulsion force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart. What is the magnitude of the electric...

To be honest, I'm in America, and our eating habits are horrible. I think it all depends on what food is "that nation's food," like for Americans, it's hamburgers. And french fries. And soda. And candy. And loads of other unhealthy stuff. Sure, eat those things once in a while, but we Americans...

I think they mean both answers could work when the equation is solved...however one answer would obviously make more sense in this case.

I would choose CS personally, but your choice!

It's from my physics homework :cry:.

Yes, sadly that's all the information I'm given, not even a diagram.

Hello! Are you, by chance, also interested in Computer Sciences? Maybe it's a coincidence, but the tradition for coders is to begin by typing in "Hello world!" the very first time they begin coding.

Homework Statement Determine the position of the center of mass of a whole leg (a) when stretched out, and (b) when bent at 90°. Assume the person is 1.70 m tall. Homework Equations The Attempt at a Solution This is where I'm stuck...what's the mass? I doubt I can just use variable m because...

OK TY all! :smile:
