Answer

$\frac{1}{2} k x^{2}$

Given: $m = 2.0 \, \mathrm{kg}$ , $k = 500 \, \mathrm{N/m}$ , $x = 0.10 \, \mathrm{m}$ , $\mu_k = 0.20$ , $g = 9.8 \, \mathrm{m/s^2}$ .

Part (1): Speed when spring returns to equilibrium length

Step 1: Initial elastic potential energy.

U_{i} = \frac{1}{2} k x^{2}

U_{i} = \frac{1}{2} (500 \, N/m) (0.10 \, m)^{2} = 2.5 \, J

Step 2: Kinetic friction force.

f_k = \mu_k m g = (0.20)(2.0 \, \
