A 5.8 x 10¹ kg train car at rest is struck from behind by a second train car, traveling at 2.6 m/s. The collision is completely inelastic so the cars stick together. The mass of the second car is 7.4 x 10¹ kg. What is the velocity of the joined trains cars immediately after the collision? Round your answer to the tenths place. m/s
Four beads, each of mass m= 1 kg, are attached at various locations to a ring, also of mass m= 1 kg, and radius R = 1 m (see figure). Find the coordinates of the center of mass of the system consisting of the ring and the beads. Angle A, located between the first bead and the horizontal, is equal to 41º. Angle B, located between the horizontal and the second bead, is equal to 48°. Angle C, located between the third bead and the horizontal, is equal to 68º. Angle D, located between the horizontal and the fourth bead, is equal to 35⁰. đa m Ycm = m d M₂ R M m₂
