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:
Initial spring potential energy at Spring #1: U1S = J
Magnitude of heat dissipated by friction after traveling across the rough surface: f∆s = J
Final spring potential energy at Spring #2 after momentarily stopping: U2S = J
