    Avg. Num. Probes to Insert in Hash Table w/ Random Collision Res. Strat.

    Oh, ok that wasn't too hard. What if \lambda = 2? Oh wait \lambda <= 1 and if \lambda = 1, that'd be infinity, which is correct. Man... still don't get it. I still think of \frac{1}{1-\lambda} as (number of total cells) / (number of empty cells), but I guess I see it as a geometric series too.

    Avg. Num. Probes to Insert in Hash Table w/ Random Collision Res. Strat.

    Hi, I'm reading Data Structures and Algorithm Analysis in Java (Second Edition) and I'm on page 178, if anyone owns the book. I know It's a computer science book and this is a math subforum, but the question is largely a mathematical one involving probability. You just need to understand what a...

    welp, guess i have to hit the books haha

    Angular velocity of a Rod after a Ball hits it.

    I remember conservation of linear momentum now from earlier this semester. I think I got it now. If not, then please just tell me what to do haha... let p be linear and L be angular momentum. before collision, p_c + L_h = m_cv_c + I_hw_h = 1*2 + 0 = 2 and after collision, L_{h+c} =...

    Find acceleration of a Block within a simply pulley system.

    Homework Statement The figure shows two blocks suspended by a cord over a pulley. The mass of black B is twice the mass of black A, m_b = 2m_a = 2m. The mass of the pulley is equal to the mass of black A, m_p = m_a = m, the radius of the pulley is R. The blocks are let free to move and the...

    Angular velocity of a Rod after a Ball hits it.

    Homework Statement A horizontal bar of mass 3.0 kg and length 1.0 m is free to rotate about a vertical axis through its center. A clay blob of mass 1.0 kg traveling at a velocity of 2.0 m/s in the direction shown collides with the end of the bar and sticks to it. Find the magnitude of the...

    Angular Momentum, Torque, and Acceleration for a Moving Body

    I don't understand that either. I didn't write that. I wrote lim r = <inf, inf, -inf> Variables in bold mean vectors. I got that from my Linear Algebra book. And inf is short for infinity. <x, y, z> is a vector with x, y, and z components.

    Angular Momentum, Torque, and Acceleration for a Moving Body

    L = m* (r x v) find r by integrating v then find L t = r x F = r x m*a find a by taking the derivative of v solve for t using r from before no, because t and F are clearly non-zero lim r = <inf, inf, -inf>
