Q. In Figure, a block slides along a path that is without friction until the block reaches thesection of length L=0.85 m, which begins at height h=2.0 m on a ramp of angle 0=45°. Inthat section, the coefficient of kinetic friction is 0.40. The block passes through point Awith a speed of 8.0 m/s. If the block can reach point B (where the friction ends), what isits speed there, and if it cannot, what is its greatest height above A?A. 8.9 m/sВ. 6.9 m/sС. 4.9 m/sD. 2.9 m/sE. 1.9 m/s

(a) What Is the speed of the object at the bottom of the incline and its acceleration along the horizontal surface? (b) What is the height of the incline?
In the figure, a 3.9 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 7.0 m/s, the height difference is h = 0.92 m, and u = 0.606. Find d. H = 0- Number i Units
While a roofer is working on a roof that slants at 32° above the horizontal, he accidentally nudges his 73N toolbox, causing it to start sliding downward, starting from rest. If it starts 5m from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18N? Answer: 5.27m/s

Q. In Figure, a block slides along a path that is without friction until the block reaches the section of length L-0.85 m, which begins at height h-2.0m on a ramp of angle 0-45, In that section, the coefficient of kinetic friction is 0.40.
