## 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
