Dear all,
I get straight to the problem, that came out of a discussion with friends:
Two bodies are in contact with masses [tex]m_1[/tex] and [tex]m_2[/tex]. Body [tex]m_2[/tex] is a pendulum. An impulsive force acts on one end of the body m_1.
(so an [tex]F\Delta t[/tex] is applied).
The bodies are elastic, after the impulsive force they both have initial velocities.
As a result the impulse is equal to: [tex]I=F\Delta t=-m_1v_1+m_2v_2[/tex].
so the pendulum(body [tex]m_2[/tex]) will have an initial kinetic energ equal to[tex]0.5m_2v_2^2[/tex]. What will be the kinetic energy of the pendulum IF I place an absorber between the two bodies?
Is it going to be the same?? this riddle has been keeping me busy for a long time..
If I place a sensor to measure the contact force vs time between the bodies [tex]m_1[/tex] and [tex]m_2[/tex] what will be the difference if there is an energy absorber in between??Is the sensor going to measure the same impulse??
Thank you all in advance
