[SOLVED] Halfway measures
Am I doing this right?
You stretch the spring of a certain mass-spring system 14.0 cm from its relaxed state; this requires 21.2J of work. You then release the system. What is its Kinetic energy when the stretch of the spring is 7 cm?
W = F*s
21.2 = F(.14)
F = 151.4N
W = 151.4(.07)
W = 10.6J
W = change in KE
KE = 10.6J
