In fig. 8-55, a block slides along a path that is without friction until the block reaches the section of length l = 0.75 m, which begins at height h = 2.0 m on a ramp of angle θ = 30°. in that section, the coefficient of kinetic friction is 0.40. the block passes through point a with a speed of 8.0 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?
