Homework Statement
An object (masse m) is placed on a slope with an angle a at a height of h above the ground. There is no friction on the inclined plane. The inclined plane leads to a horizontal plane 2 meters long that ends with a spring with a constant of k. There is friction on the horizontal plane (but not the inclined plane). Where is the object when its velocity is equal to 1m/s?
m=1kg
h=0.5m
k=1000N/m
angle a= 30 degrees
F(friction)=1N
Homework Equations
E(kin)=0.5*mv²
W = E(cin final) - E(cin initial)
The Attempt at a Solution
W = 0.5*mv² - 0.5*m(0)²
=0.5*mv² = F*d
d=(mv²)/(2F)
=.5m
but I don't know how to add in the energie given by the spring and the energy lost from friction.
Any help would be appreciated thanks
