In the figure a block slides along a path that is without friction until the block reaches the section of length L = 0.69 m, which begins at heighth = 1.4 m, on a ramp of angle 0 = 32 . In that section the coefficient of kinetic friction is 0.310. The block passes through point A with a speed of 8.2 m/s. If the block can reach point B (where the friction ends), what is its speed there, and if it cannot, what is its greatest height above A? Number Unit v
