From the information given, the mass of the hammer seems to be 1.36 kg and the velocity by which it is wielded seems to be 22 m/s.
The most suitable formula to be used here is :
f = m × v
where f is force, m is mass and v is velocity.
f = m × v → f = 1.36 × 22 → f = 29.92 kg m/s
Therefore the force generated by the hammer is 29.92 N
( kg m/s is the same as Newton)
