I have a question for anyone that is familiar with MATLAB. I'm trying to do some simple integration in MATLAB (and if your wondering why I don't just do it by hand, it is because I want to implement the same code for a wide variety of functions). The problem is when using int(a) in matlab, it...

Thank you very much. That helped me out a lot. I couldn't not figure that out at all. Thanks again.

Homework Statement What is the thinnest film of a coating with n = 1.43 on glass (n=1.52) for which destructive interference of the red component (660 nm) of an incident white light beam in air can take place by reflection? Homework Equations 2t = m*lambda? The Attempt at a...

Homework Statement A belt passes over two pulleys O1 (radius R1= 0.4 m) and O2 (radius R2 = 0.6 m) as shown, and points A and B are on the rim of the pulleys. The normal acceleration at A is 0.9 m/s2 and the angular acceleration of pulley O1 is 3.6 rad/s2. Find (a) the belt velocity υb, (b)...

Ok I got it now. Thanks for the help.

Homework Statement The frictionless track is made of a straight horizontal section and a quarter-circle with radius R = 5 m. A 1 Kg lump of putty is thrown toward the stationary 4 Kg block, and the block starts to slide with the putty stuck on it after the collision. If the normal force acting...
