1. The problem statement, all variables and given/known data 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? 2. Relevant equations Conservation of mechanical energy...1/2mv0^2 + mgh0 = 1/2mvf+mghf. 3. 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!
