Thanks for replying, faust. What I'm trying to do is place three shelves, with straight backs, following the back wall like in the picture. What's getting me are those two corners (one in the left and one in the right) where there's dead space. I need to find an accurate width for each shelf so...
Clarification
Maybe this will clear up some things; http://img.photobucket.com/albums/v449/MJF/shelfplacement.gif [Broken]
All the images I have linked to are top-down views of the closet. I need three shelves, all of the same width. Looking at the picture, you can see that the corners of...
Hi, I've been trying to work this problem that someone needs for a closet project. I tried to get some help in the general math forum, but that didn't work. Hopefully I'm targeting the right group now :)
Basically we're trying to build custom (cut to fit) shelves in a walk-in closet. There's...
Ok, I think I got it now. Final velocity of mass one in the x-direction is 0.6 m/s, and for the y-direction 0.8 m/s.
Conservation of momentum in the x-direction;
m_1v_1_x_i+m_2v_2_x_i=m_1v_1_x_f+m_2v_2_x_f
Solve for v_2_x_f, and I get 0.933 m/s.
Do the above, only now for velocity...
I have a bit of a problem with this question:
A 0.30-kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20-kg puck that is intitially moving along the x-axis with a velocity of 2.0 m/s. After the collision, the 0.20-kg puck has a speed of 1 m/s at an angle of 53...
If you ever look at pictures of Omaha beach you can see that the terrain is very suitable for defense. There were 100 ft. cliffs with only five exits. Omaha was defended by a crack German force, while other spots were manned by troops with less training, sometimes very little at all. Also...
I'll try and clear this up a bit more. The whole experiment is working with an Atwood device. I just realized that I totally messed up in one area. In this experiment I needed to variate the masses, which I forgot to do. Thus, I have the same two masses for each different height.
So, when I...
I'm sorry but I think there's a little misunderstanding :). I already HAVE the acceleration taken from average velocity vs time. I did as you suggested and did v/t and d/t, but neither gives the right slope. I may have totally missed something, but I don't get it.
What I have are fifteen...
Hi, I'm having a bit of a problem with an experiment I recently did. Basically I had two objects on a pulley (let's say masses M and m, M being the heavier object), at five different heights. I released the objects three times for each height. I then calculated the acceleration for each separate...
Hi, I'm working on a project involving a two-weight pulley system. The idea is to take two washers of slightly different masses and devise a method of determining a numerical value for the acceleration of gravity using the pulley. Basically the pulley slows down the effect of gravity, and I need...
Hi, I have a homework problem that's giving me a bit of trouble. I hope someone can help me out and verify whether I'm correct or not :)
After falling from rest at a height of 30 meters, a 0.50 kilogram ball rebounds upward, reaching a height of 20 meters. If the contact between ball and...
