To solve the problem, we will follow these steps: ### Step 1: Identify the given data - Mass of the block (m) = 20 kg - Initial velocity (u) = 0 m/s (starting from rest) - Final velocity (v) = 1 m/s - Height descended (h) = 5 m - Acceleration due to gravity (g) = 10 m/s² (assuming standard value) ...
