    Momentum P = m*V = 0.028*8.4 = 0.24 kg*m/sec

    Probably best to answer in KMS system.

    28g (1 kg/1000g) = 0.028 kg

    P = mv

    P = 0.028 kg * 8.4 m/s = 0.2352

    Now round to 2 sigfigs: 0.24 kg m/s

    momentum = mass * velocity

    = (0.028 kg)(8.4 m/s)

    = 0.2352 kg m/s

    ≈ 0.24 kg m/s (with 2 sig fig)
