15.5.7. The slider 1 2 kg is connected to a hinge with a uniform rod AB of length 2 = 1 m and a weight of 6 kg. The end of the rod slides along the horizontal plane. To determine the kinetic energy of the bodies of the system when the velocity vA = 1 m / s and an angle φ = 60 °.

Right after the payment you will receive a link to a zip archive with the solution of the problem 15.5.7
