Homework Statement
An object of mass m = 2kg is relesed from a height h=5m and left to slide on a frictionless curved ramp.
Once it reaches the bottom it slides horizontally from point A to point B, covering a distance L=6m on a surface with kinetic friction coefficient [PLAIN]https://upload.wikimedia.org/math/3/a/d/3ad4fa5a7787192d8cbb5f69d33d05cc.png= 1/3.
To the right of point B, the friction becomes negligible and the object comes into contact with a relaxed spring of spring constant k=30 N/m .
Take g=10 m/x²
a-) Find the max compression of spring
b-)As the spring decompresses, it imparts a leftward velocity to the object. Can the object reach point A with that speed?
2. Homework Equations
F=-kx
Work done by friction =
The Attempt at a Solution
I found :
Work done by friction = 40
Ek = 100
final energy =Ek-W = 100 - 40 = 60
Then
60 = 1/2 k x2
I could not find b
Help please
and thanks :)
