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?

In the figure shown, a mass m1 = 2 kg slides up a frictionless track until it collides with and stick to m2 = 4 kg, which is sitting at rest at height h = 2 m on a ramp of angle θ = 30∘, as shown in the figure. After the collision the two blocks moved together to point B a distance L = 0.05 m where the coefficient of kinetic friction is 0.4. If ml has a speed of 8 m/s at point A, find: a) The impulse delivered to m2 as a result of the collision. b) Use energy concepts to determine the speed of m2 and m1 at point B.
