As we know, momentum= massvelocity 
acc. to ques. mass = 2kg 
momentum= 25kg-m/s 
momentum = massvelocity (speed) 
velocity (speed) = momentum/mass 
velocity(speed)=25/2 
=12.5m/s

                       Momentum = (mass) x (speed)

                        (25 kg-m/s) = (2.0 kg) x (speed)

                           Speed = (25 kg-m/s) / (2.0 kg)  =  12.5 m/s
