Question
A block of mass 2kg is pushed against a light spring of
spring constant 200N/m and compressed by 0.2m on a horizontal surface with kinetic friction coefficient μk =0.1. When the spring is released, what is the maximum speed attained by the block?Solution
We are given:
- Mass of block: m = 2 kg
- Spring constant: k = 200 N/m
- Compression: x = 0.2 m
- Coefficient of kinetic friction: μk = 0.1
- Surface: horizontal (so normal force = mg)
- Objective: Find the maximum speed attained by the block as the spring releases.
