when a 0.05kg bullet is fired into a block that is suspended by a long cord so that it can swing as a pendulum. if the block is displaced so that its centre of gravity rises by 0.10m,what was the speed of the bullet?

  • mass of block? -

    Need to know mass of the block to do conservation of momentum.

  • physics -

    565

  • physics -

    (281.4m/s)
