The position of a 50 g oscillating mass is given by x(t)=(2.0cm)cos(10t−π/4), where t is in s. If necessary, round your answers to three significant figures. Determine: The total energy.
T = 2π/w
T = 2π√m/k
The Attempt at a Solution
T = 2π/10 = 0.6283s
k = 0.5kg / (0.6823/2π)^2 = 5.000N/m
1/2kA^2 = 0.5(5)(0.02)^2 = 0.001J
