1. A 14.7g mass is attached to a frictionless horizontal spring. After the spring was stretched a certain distance and released, its maximum speed was found to be 4.22 m/s. If the speed at x = -2.84 cm is 1.63 m/s, what is the frequency of the oscillating spring?
2. PEe = kx^2/2 E=KE + PE E=mV^2/2 + kx^2/2 (E is conserved) f = 1/3.14 sq. rt of k/m
3. (.0147kg)(-.0284m)^2/2 = .000005928 J
I don't know how to get (k) and honestly have no idea where to start this problem.
