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).
Take the difference among your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to be 8m/s
