Question
A block (2 kg) initially compresses spring #1 (k = 1000 N/m) by 60 cm from its equilibrium point. When the block is released, it slides a total horizontal distance of 1.5 m on a rough surface with a kinetic coefficient of friction μₖ = 0.5. The block then compresses a stiffer spring #2 and momentarily stops. Find the following numerical energy values of the block:

1. **Initial spring potential energy at Spring #1:**  
   \( U_{1S} = \) _____ J  
   [Submit Answer] Tries 0/2

2. **Magnitude of heat dissipated by friction after traveling across the rough surface:**  
   \( f \Delta s = \) _____ J  
   [Submit Answer] Tries 0/2

3. **Final spring potential energy at Spring #2 after momentarily stopping:**  
   \( U_{2S} = \) _____ J  
   [Submit Answer] Tries 0/2
