Freight car A of mass m is rolling to the right when it collides with freight car B of mass 1.62m initially at rest. If the two cars are coupled together at impact, find the fractional loss of energy n during the collision. B Answer: n = the tolerance is +/-2%
In an emergency, the gas actuator is used to move a 75 kg B block through the explosion a charge C near a cylinder pressurized of negligible mass. Like result of the explosion, the fractured part of the cylinder and released gas force the front of the cylinder, A, moving forward to B, giving you a speed of 200 mm s in 0.4 s. If the coefficient of kinetic friction between B and the ground is μc = 0.5, determine the pulse that the actuator transmits to B.

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Block A has a mass of 16 kg, and blocks B and Chave masses of 8 kg each. Assume that the blocks are initially at rest and that B moves through 3 m in 2 s. Neglect the masses of the pulleys and the axle friction. B P D C Determine the tension in the cord AD. The tension in the cord AD is TEN.
Starting from rest, it takes 1 second for m1 to fall 1.5m. A ring of unknown mass sits on top of m1 as it falls. If m1=2kg and m2=2.5kg, and the incline is frictionless, what force does m1 put on the ring?
