The vibration period of that weight is the time in which it makes a complete cycle in motion. Suppose the relationship between the vibration period "T" (in seconds) and the weight "w" (in kilograms) is given by T = 2(w / 200). Find the period T, EXACT and approximate to the nearest thousandth, for a spring with a hanging weight of 2.0 kilograms. Be sure to show your work and include units of measurement to earn full credit. (3 pts) a Find the EXACT period T (with in the answer) for a spring with a hanging weight of 2.0 kilograms.
