    Design a $40 Egg-Protecting Device for the Egg Drop Challenge

    I did this project as well and put the egg inside a box filled with sponge. On the outside of the box I cut out pieces of an egg carton and put one on each side (the dome shape is the strongest)

    Difficult circular motion problem

    How did you get T=\frac{mv^2}{Lsin^2\theta} I solved for T in the y direction and got T=\frac{mg}{cos\theta} \frac{mg}{cos\theta}*{sin\theta}==\frac{mv^2}{Lsin\theta} I'm stuck after this I can't seem to get the sin into a quadratic equation

    Physics Problem on Angular Momentum

    Homework Statement A uniform 4.5 kg square solid wooden gate 1.5 m on each side hangs vertically from a frictionless pivot at the center of its upper edge. A 1.1 kg raven flying horizontally at 5.0 m/s flies into this gate at its center and bounces back at 2.0 m/s in the opposite direction...

    Kinematics: acceleration on a an incline (LAB)

    I figured out my mistake, I switched the distance and time on the first graph. Thank you all for your help I really appreciate it !

    Kinematics: acceleration on a an incline (LAB)

    yes it was. There is a second part to the lab where the inital velocity is not equal to 0. I used the same angle of 0.055 and found the value of g as 9.45 m/s^2. So now I don't believe the angle is wrong but there might be an error with the length or timing

    This is exactly what my set up looked like. http://imageshack.us/photo/my-images/440/inclinedplane2.gif/

    Kinematics: acceleration on a an incline (LAB)

    Hey thanks for the reply! The problem is actually that my answer is 115 METERS per second which is why I was saying it was way off the original number. It looks like there is a decimal error but I converted cm to meters correctly. For the theta (in the diagram) the 69.47 cm is the hypotenuse...

    Kinematics: acceleration on a an incline (LAB)

    Homework Statement Hey guys, I'm having a problem with my lab report write-up. The purpose of the lab is to find the value of g which should be around 9.8 m/s^2. This was found by releasing a cart from rest on an inclined plane and measuring the time it took to travel across a certain...
