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).
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
