Question about spring compression

Click For Summary
SUMMARY

A 12 kg block slides down a frictionless incline at a 35-degree angle and compresses a spring with a constant of 3.00x10^4 N/m after traveling 3 meters. The problem can be solved using the work-energy principle, specifically the equation for spring potential energy, Ws = 1/2 kxmax². The gravitational potential energy (GPE) of the block decreases as it descends, converting into kinetic energy, which is then transferred to the spring as it compresses. The total energy conservation approach effectively illustrates the relationship between the block's GPE, kinetic energy, and the spring's potential energy.

A 12 kg block slides from rest down frictionless 35 degree incline and is stopped by spring w/ constant of 3.00x10^4 N/m. The block slides 3 m from the point of release to the point of rest against spring, how far has spring compressed?

Now I know this involves the equation Ws= 1/2kxmax2, but I am not sure where to go from there.
 
Physics news on Phys.org
The block starts at rest and accelerates on a frictionless plane/incline. One could determined the acceleration of the block down the incline (F/m) and the velocity at the distance traveled.

Another way to do this is to apply conservation of energy. At the beginning, the energy of the block is simply gravitational potential energy (GPE). When block to the spring, it decreases in elevation, so its GPE changes, and that changes equals the increase in kinetic energy.

When the block compresses the spring, its kinetic energy is transformed into the springs potential energy.
