Two particles of equal masses m1=m2 move on a frictionless horizontal surface in the vicinity of a fixed force center, with potential energies U1 = 1/2kr^(2)1 and U2 = 1/2kr^(2)2. In addition they interact with each other via a potential energy U12 = 1/2αkr^2 where r is the distance between them and α and k are positive constants. (a) Find the Lagrangian in terms of the CM position R and the relative position r. (b) Write down and solve the...

Two masses, m1 and m2, are falling but not freely. In addition to gravity, there is also a force F1 applied directly to m1 in the downward direction and a force F2 applied directly to m2 in the horizontal direction. Friction (µs) is present between the two masses and the forces are applied such that they do not rotate. The force F2 is as large as it can be and not have m2 slide relative to m1. (a) Find an...

two masses m1 = 4.70 kg and m2 which has a mass 50.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h = 2.90 m, use energy content to determine the following. (a) speed v of the masses (b) magnitude of the tension T in the cord

1. Suppose we have two blocks of masses m1 and m2. The block with mass m1 is moving towards block m2 at speed v. After the collision, we measure the total kinetic energy and find that the total kinetic energy after the collision is m2/(m1+m2) less than the kinetic energy before the collision. Find the final speeds of the two blocks. What type of collision is this? 2. Explain, in words, how we know that a freely spinning asteroid in...

Two objects with masses of m1 = 3.20 kg and m2 = 7.90 kg are connected by a light string that passes over a frictionless pulley, as in the figure below. A string passes over a pulley which is suspended from a horizontal surface. A circular object of mass m1 and a rectangular object of m2 are, respectively, attached to the left and right ends of the string. (a) Determine the tension in the string. N (b) Determine the acceleration...

two masses m1 and m2 move under their mutual gravitation attraction in a uniform external gravitational field whose acceleration is g. Choose as coordinates the cartesian coordinates X, Y, Z, of the center of mass (taking Z in the direction of g), the distance r between m1 and m2, and the polar angles θ and φ which specify the direction of the line from m1 to m2. Write expressions for the kinetic energy, the six forces Q_x, ... ,Q_φ and...
