PS is the BHP(Brake Horse power) OS the vehicle eg: 100PS@5500rpm means the vehicle delivers 100bhp of max power when the engine runs at 5500rpm(revolutions per minute) PS and BHP are unit of power NM or KGM are units of torque 130NM@2000rpm means the vehicle delivers max torque of 130 NM(Newton meter) at 2000 rpm 130NM can also be written as 13Kgm(Kilogram meter)

Momentum is mass multiplied by velocity. The momentum of the two ships would be 300 x 2 = 600 kgm/s and 300 x 1 = 300 kgm/s. So the combined momentum of the two ships would be 900 kgm/s.
