## Homework Statement

A 2.6kg block slides along a frictionless horizontal with a speed of 2.9m/s. After sliding a distance of 6m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 12 degrees to the horizontal. How far up the ramp does the block slide before coming momentarily to rest?

## Homework Equations

Conservation of mechanical energy...1/2mv0^2 + mgh0 = 1/2mvf+mghf.

## The Attempt at a Solution

I know that V0 = 26, Vf = 0, but I don't know what h is. Is there another approach to this problem?

Thank you so much!
