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).
Diffraction is the spreading of light that takes place when it pass through a thin slit or small hole or passes by an obstacle Answer: Diffraction is the spreading of any k
