5.) A block slides along a path that B/ 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 0 = 20°. 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?

5.) A block slides along a path that
is without friction until the block
reaches the section L
BA
0.80 m,
which begins at a height h = 2.5 m
on a ramp of angle 0 = 20°. 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?
