AI Thread Summary
To solve the collision physics problem involving masses A and C, the initial velocities need to be evaluated before and after the impact. Mass A, weighing 10 kg, swings down and collides with mass C, which weighs 20 kg, with a coefficient of restitution of 0.5 indicating the collision is inelastic. The final velocities calculated are 0 m/s for mass A and approximately 3.13 m/s for mass C. The discussion emphasizes the need to understand the difference between elastic and inelastic collisions, confirming that this scenario is inelastic. Proper application of the coefficient of restitution is crucial for determining the velocities post-impact.

Homework Statement


A mass a of 10 kg mass, is attached by a cord to B. When released A swings down and collides with mass c of 20 kg mass which is vertically below B. if the coefficient of restitution is 0.5 and A and C are assumed to be point masses, determine the velocity of A and C immediately after impact.

Answer is - A 0 m/s, C- 3.13m/s but i do not know hot to get it.



Homework Equations





The Attempt at a Solution



I know that we evaluate the situation before impact and after impact.
Can someone help? Also I need to know if it is elastic or not.
 
Physics news on Phys.org
so that means that we have to find the difference in the initial velocity and final velocity for both objects right?

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
