How Does a Spring System Work on an Inclined Plane?

Click For Summary
SUMMARY

The discussion focuses on the mechanics of a spring system mounted on a frictionless incline at an angle of 29 degrees, specifically analyzing a mass of 4.6 kg propelled by a spring with a constant of 560 N/m. The key equations involved include the spring potential energy formula W = 1/2 kx², where k is the spring constant and x is the compression distance. The participants emphasize the importance of conservation of energy principles, noting that energy can exist in spring potential, kinetic, and gravitational potential forms. The discussion aims to determine the mass's velocity upon leaving the spring and the maximum distance it travels up the incline.

PREREQUISITES
  • Understanding of spring potential energy (W = 1/2 kx²)
  • Knowledge of kinetic energy and gravitational potential energy formulas
  • Familiarity with conservation of energy principles
  • Basic understanding of inclined plane mechanics
NEXT STEPS
  • Calculate the velocity of the mass using energy conservation principles.
  • Determine the maximum height reached by the mass on the incline using gravitational potential energy.
  • Explore the effects of different spring constants on the system's dynamics.
  • Investigate the impact of friction on inclined plane problems.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and energy conservation, as well as educators seeking to enhance their understanding of spring systems on inclined planes.

Homework Statement



A spring is mounted at an angle of 29 degrees on a frictionless incline as illustrated in the figure below. The spring is compressed to 15 cm where it is allowed to propel a mass of 4.6 kg up the incline.

Homework Equations



All I am really aware of is W=1/2kx2

But i do not know where to go from there

The Attempt at a Solution



Idk..i really need some guidance..THANKS!
 
Physics news on Phys.org
Sorry i forgot the questions!

(a) If the spring constant is 560 N/m, how fast is the mass moving when leaves the spring?

(b) To what maximum distance from the starting point will the mass rise up the incline?
 
loosk like a good one for conservation of energy

at each point the energy can be in 3 forms

spring potential energy, kinetic energy & gravitation potential energy

should know the formulas for each of these think about where they apply
 
i tried that and I am not getting the right answer..i figured i would have to find the velocity in x and y before i find THE velocity..but i don't know where to start with that
 
show your working then...

this should be a 1D problem, set up your coordinate system at the incline

the Grav Potential will be the only place the angle enters into
