Question
Your answer is partially correct.
In the figure a block slides along a path that is without friction until the block reaches the
section of length L = 0.66 m, which begins at height h = 1.1 m, on a ramp of angle 0 = 32°.
In that section the coefficient of kinetic friction is 0.410. The block passes through point A
with a speed of 8.4 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?
