A 2.1 kg block slides along a horizontal surface with a coefficient of kinetic friction μk = 0.31. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.
Explain why the detachment occurs when the spring reaches its natural length (x = 0).
Poisson spot (S.D. Poisson) Originally Poisson predicted the existence of such spot, and utilized the prediction to revel how the wave theory of light have to be in error to g
