Problem 1:
In the Figure below 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 m on a ramp of angle 0 = 30°.
In that section, the coefficient of kinetic friction is 0.40. The block passes through point A with a
speed of 8 m/sec. What is the speed of the block at point B (where the friction ends)?
Answer: 3.5 m/sec
