A block A, of mass m = 10 Kg, compresses a spring of constant K = 1000 N / m in a length x = 3 cm. Starting from rest, the block is released, which moves from that moment on a horizontal surface without friction until it collides with another block B of mass m = 40 Kg, which was at rest. (Perfectly inelastic shock) and together they go up the channel (inclined surface) without friction, to later continue along a second horizontal plane without friction, at a height h with respect to the first (see Figure). Determine the energy variation that occurs in the collision .
A brick of mass m = 0.48 kg is set against a spring with a spring constant of k1 = 619 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 244 N/m. The brick is not connected to the first spring and may slide freely. Now assume friction is present on the surface in between the ends of the springs at their equilibrium lengths, and the coefficient of kinetic friction is μk = 0.5. If the distance between the springs is x = 1 m, how far d2, in meters, will the second spring now compress?

The figure shows a system of masses. The mass of 2m is connected to an immobile wall with a spring of constant 2k, while the mass of m is connected to an immobile wall with a spring of constant k. The masses are then coupled to each other with an elastic band of length L, under tension T =2kL. The masses are constrained to move in the x direction only. At equilibrium. the masses have the same x position and the springs are uncompressed. There is no friction or gravity. The displacements from equilibrium are small enough (x1, x2 << L), so that the tension in the band stays constant. 1-Write down the coupled differential equations describing the displacement of the masses from equilibrium {x1, x2}.

An object with mass m = 5.0 kg is released from rest from a height H = 11 m as shown in the figure. It slides down the incline at angle θ = 38° and collides with a spring that has a spring constant k = 1400 N/m. The coefficient of kinetic friction is not constant over the incline, but increases linearly with a distance as μ k (x) = αx, where α is constant and its value is 0.049 m −1 and x is distance in meters. The horizontal surface is frictionless. What is the work done by the friction force as the block slides from point A to point B? (Your result must be in Joules and without decimals.
