    Collision Spring
AI Thread Summary
The discussion revolves around calculating the final velocity of a ball and a stationary steel plate after a collision, considering parameters such as the mass of the ball, the mass of the plate, the angle of impact, the coefficient of restitution, and spring stiffness. The initial conditions include a ball striking the plate at 30 m/s and an angle of 60 degrees, with the plate having two different mass scenarios (M=2m and M=0.5m). Participants are seeking help with the calculations for the final velocities and spring deflection resulting from the impact. Visual aids, like a setup diagram, are requested to better understand the problem. The discussion emphasizes the need for clarity in applying physics concepts to solve the collision scenario.

View attachment 2501The ball (mass m) strikes the heavy steel plate (mass M) with a velocity of v=30m/s at an angle of 60 degrees with the horizontal. the plate is initially stationary. If the coefficient of restitution is e=0.7 and the spring stiffness is k=155N/m. Calculate the final velocity of the ball and the plate immediately after impact and the spring deflection. Also do the calculations if M=2m and M=0.5m

i just need a kick start on this question as I am completely lost

Please post a picture of the setup.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
