Springs & Elastic Potential Energy Video Lessons

Example

# Problem: A 2.00-kg package is released on a 53.1 53.1 s = 0.40 incline, 4.00 m from a long spring with force constant 120 N/m that is attached at the bottom of the incline . The coefficients of friction between the package and the incline are k = 0.20 and mu_{k} ;=; 0.20. The mass of the spring is negligible.What is the speed of the package just before it reaches the spring?What is the maximum compression of the spring?The package rebounds back up the incline. How close does it get to its initial position?

###### Problem Details

A 2.00-kg package is released on a 53.1 53.1 s = 0.40 incline, 4.00 m from a long spring with force constant 120 N/m that is attached at the bottom of the incline . The coefficients of friction between the package and the incline are k = 0.20 and . The mass of the spring is negligible.

What is the speed of the package just before it reaches the spring?

What is the maximum compression of the spring?

The package rebounds back up the incline. How close does it get to its initial position?
