    Can Conservation of Momentum Solve This Collision Problem?

    Homework Statement Two particles of mass m, connected by a rod of lengh L, are at rest. Another particle of mass m moving at v0 strikes one of the particles at a right angle and sticks to it. a) Find the linear velocity, angular velocity about center of mass. b) which point is momentarily...

    What do you do when time is present in Lagragian Equation?

    I understand the throw away, but when I differentiate dL/dq - d/dt (dL/dq dot) = 0 do I care about time at all?

    What do you do when time is present in Lagragian Equation?

    I set up a Lagragian equation that involves time t. What do I do? I only know how to solve Lagragian equation in the absence of time. Please help.

    Does This Lagrange's Equation for a Spring Pendulum Look Correct?

    A pendulum consists of a mass m suspended by a massless spring with unextended length b and. spring constant k. Find Lagrange’s equations of motion Here's how I set up my equation: x = lsin(theta) y = -lcos(theta) (x=0 at equilibrium, y=0 at the point wehre the pendulum is hung from)...

    How Do Gauss' and Stokes' Theorems Apply to These Integral Problems?

    Hi guys, I am having trouble with this "simple" problem involving these two theorems: Find the value of the integral (A dot da) over the surface s, where A = xi - yj + zk and S is the closed surface defined by the cylinder c^2 = x^2 + y^2. The top and bottom of the cylinder are z= 0 and...
