Verified Answer :

225/50=4.5
because if u look at the units, the kg will be cancelled out if u divide the momentum by mass, leaving you with m/s

|Momentum| = (mass) x (speed)

225 kg-m/s =(50kg) x (speed)

Divide each side by (50kg):  Speed=(225 kg-m/s) / (50 kg) = 4.5 m/s .

Regarding the velocity, nothing can be said other than the speed, because
we have no information regarding the direction of the object's motion.
