Two blocks undergo a completely inelastic collision while sliding horizontally on a smooth surface. Before the collision, block A is sliding to the right at 6 m/s whereas block B is sliding to the left at 17 m/s. The mass of block A is 8 kg and the mass of block B is 7 kg, calculate their post-collision speed

    Two boxes are sliding to the right on a horizontal frictionless surface. Box 1 is trailing box 2. Box 1 has a mass of 2 kg and a speed of 5 m/s, while box 2 has a mass of 4 kg and a speed of 3 m/s. Eventually, box 1 catches up to box 2 and experiences a completely inelastic collision with box 2. What is the speed of the two blocks after the collision?

  • 3 Block Inelastic collision

    A block of massm1 = 1.30kg moving at v1 = 2.00m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.100kg . The blocks then move, stuck together,at speed . After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60kg , which is initially at rest. The three blocksthen move, stuck together, with speed v3 . Assume that the blocks slide without friction.Find v1/v2, the ratio of the...
