A 3.0 kg block slides down a 4.5 m ramp of angle 30 degrees and collides inelastically with a 4.5 kg bolck at rest.

Calculate the velocity after the collision.

  • Physics -

    The kinetic energy of the 3kg block will be
    KE = 3*9.8*4.5*sin30 at the bottom, before collision. Use this to compute its velocity at that time. Then use conservation of mo momentum for the collision. Ou
