A baseball bat balances 61.1 cm from one end. If a 0.600 kg glove is attached to that end, the balance point moves 22.7 cm toward the glove. Find the mass of the bat.

  • Physics -

    The Center of Mass of the bat (alone) is 61.1 cm from the end where the glove is hung.

    With the glove there, the balance point moves to 61.1-22.7 = 38.4 cm from that end.

    The torque about the new balance point is
    Mbat*22.7 - 0.600*38.4 = 0
    Therefore,
    Mbat = 0.600kg*38.4/22.7 = 1.015 kg
