Ablock slides along a path that is without friction until the block reaches the section l = 0.80 m, which begins at a height h = 2.5 m on a ramp of angle θ = 20 o . in that section, the coefficient of kinetic friction is 0.50. 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 the speed there, and if it cannot, what is its greatest height above a?
