A bullet A of mass 2kg travelling at 200m/s emblezes itself in a wooden block of mass 9kg moving in the opposite direction. At 20m/s. Calculate the velocity of the block when the bullet comes to rest inside the block. And what principle is used in the direction

  • physics - ,

    Initial momentum
    = 2(200) -9(20) = 400 - 180 = 220

    final momentum = 11 v

    Conservation of momentum, Newton's First Law --->

    220 = 11 v
    so
    v = 20 m/s
