SUMMARY
The discussion focuses on calculating the spring constant (k) for a block compressing a spring after sliding on a rough surface. Given a 1.8 kg block with an initial speed of 2.0 m/s, it compresses the spring by 0.11 m before stopping. The coefficient of friction is 0.560. The kinetic energy (Ek) of the block is calculated as 3.6 J using the equation Ek = 1/2 mv², and the frictional force is determined using Ff = μFn, where Fn equals the gravitational force acting on the block.
PREREQUISITES
- Understanding of kinetic energy (Ek = 1/2 mv²)
