After sliding down a snow covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.7 m/s. Miranda runs after her at a velocity of +45 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashleys mass is 71 kg and Mirandas is 58 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow

  • Mechanics: 3 Probles on conservation of energy and momentum

    52708 Mechanics: 3 Probles on conservation of energy and momentum. Collisions are discussed in detail. (See attached files for full problem descriptions with diagrams, units and proper equations) --- Let two particles of equal mass collide.

  • Special Relativity - Energy Problems.

    rest is 0, hence the total initial momentum of the system is: In relativity, both total momentum and total energy are conserved regardless of the type of collision (in classical mechanics energy is not conserved in inelastic collisions like

  • Object Velocities

    Using the conservation of energy law we can thus see that the kinetic energy of object #1 just before the collision is equal to 7.84 J = 0.5 * 1 * v1 ^ 2.

  • Relativistic mechanics kinetic energy

    the particle: (1.22) We get in the lab frame: (1.23) The expert states the conservation of momentum and kinetic energy in collision in classical mechanics and relativistic mechanics.

    Is it possible for both objects to be at rest after the collision? Explain using the principle of conservation of momentum.

  • Impulse Momentum, Conservation of Linear Momentum, & Collisions

    before collision = 0 Initial momentum of the bullet before collision = v01m1 Final momentum of block + bullet = (m1+m2)vf By conservation of linear momentum: Net momentum before collision = Net momentum after collision v01m1 = (m1+m2)vf

  • Momentum, velocity, and kinetic energy of the system after a collision

    After the collision the balls will have a mass M = 1kg and a velocity we will call V. Conservation of momentum says Pb = Pa, that is the momentum before equals the momentum after the collision.
