In the figure here, a small block is sent through point A with a speed of 6.4 m/s. Its path is without friction until it reaches the section of length L = 14 m, where the coefficient of kinetic friction is 0.75. The indicated heights are h1 = 5.4 m and h2 = 2.2 m. What are the speeds of the block at (a) point B and (b) point C? (c) Does the block reach point D? (d) If so, what is its speed there if not, how far through the section of friction does it travel? (a) Number Unit (b) Number Unit (c)

In the figure here, a small block is sent through point A with a speed of 6.2 m/s. Its path is without friction until it reaches the section of length L = 13 m, where the coefficient of kinetic friction is 0.75. The indicated heights are h1 = 5.2 m and h2 = 2.9 m. What are the speeds of the block at (a) point B and (b) point C? (c) Does the block reach point D? (d) If so, what is its speed there; if not, how far through the section of friction does it travel?

In the figure a block slides along a path that is without friction until the block reaches the section of length L = 0.77 m, which begins at height h = 1.2 m, on a ramp of angle θ = 30∘. In that section the coefficient of kinetic friction is 0.480. 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?

The figure here shows a plot of potential energy U versus position x of a 0.884 kg particle that can travel only along an x axis. (Nonconservative forces are not involved.) Three values are UA = 15.0 J, UB = 35.0 J and UC = 45.0 J. The particle is released at x = 4.50 m with an initial speed of 7.82 m/s, headed in the negative x direction. (a) If the particle can reach x = 1.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (b) magnitude and (c) direction of the force on the particle as it begins to move to the left of x = 4.00 m? Suppose, instead, the particle is headed in the positive x direction when it is released at x = 4.50 m at speed 7.82 m/s. (d) If the particle can reach x = 7.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (e) magnitude and (f) direction of the force on the particle as it begins to move to the right of x = 5.00 m? (a) Number Unit (b) Number Unit (c) (d) Number Unit (e) Number Unit (f)
