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. The minimum wavelength of X-rays produced in a Coolidge tube is 0.05 nm. Find the operating voltage of the Coolidge tube. λmin = 12400 A 0 / V = 0.5 X 10 -10 m Theref
