DIRE NEED of HELP on HARDEST Physics Problem Ever
My class didn't get very far. I was disappointed, as I am taking AP Physics C: Mechanics, so I could not really help out as I haven't done E&M at all this year. It was pretty much up to Honors physics students who are currently studying capacitance. Anyway, I have a copy of the solution now...- brendan3eb

DIRE NEED of HELP on HARDEST Physics Problem Ever
Ok, the seniors just gave us the answer. I may be back with another problem later, but I think this it for now. the answer was .46 rad/s- brendan3eb

DIRE NEED of HELP on HARDEST Physics Problem Ever
Ok, so I am in the middle of what is known as the "axe hunt" at my school. It is the culminating event of the year. The seniors puts together a scavenger hunt that is supposed to take 24 hours consisting of various clues that will require juniors to use their athletic and intellectual...- brendan3eb

Solve Spring SHM Problem: Period of Oscillation in M1, M2, k
Homework Statement Two blocks of mass M2 and M1 (M2>M1) are connected by a spring with force constant k and are free to slide on a frictionless table. They are pulled apart and then released from rest. In terms of M1, M2, and k, what would the period of oscillation be? Homework...- brendan3eb

What Is the Magnitude of the Average Acceleration of a Ball Bouncing Off a Wall?
I am not sure if you have gotten to impulse, but if you have, then you can solve with those equations. Recall that linear momentum J equals the change in impulse - J=mv2-mv1 Also remember that J=Favg*T You'll have solved for J, and you already know that T=3 ms, so you should be able to find...- brendan3eb

How Does Gravity Affect Equations in Vertical SHM Problems?
I have been doing quite a few SHM problems, and I just have a few questions in general. A lot of questions evolved from one particular problem type: A mass attached to the end of a vertical spring of spring constant k. My questions: 1. How can we prove that we can use the equation...- brendan3eb

Can Calculus Validate the Proof of w=(k/m)^(1/2) in SHM Equations?
So I am attempting to prove the simple harmonic motion equations with calculus so as to develop a better understanding of shm problems and have more flexibility when it comes to solving them. I am having a bit of trouble understanding the proof of w=(k/m)^(1/2) Here is how I am doing it. I...- brendan3eb

Direction of Rolling/Sliding Friction
This much more of a general question that I've encountered in quite a few problems and I haven't found an answer to in my books or searching the net yet. Take, for example, a ball that has been propelled into motion by a spring gun on the floor. Initially, the ball accelerates so that the ball...- brendan3eb

Graph of Kinetic Energy v. Displacement of a Falling Object
ahh.. v^2=v0^2+2a(x-x0) but since initial velocity in the y direction is 0 v^2=-2g(x-x0) and since -2g is a constant, v^2 is directly proportional to displacement, and thus kinetic energy is directly proportional to displacement! Thanks Doc Al!- brendan3eb
