use conservation of momentum.
masspackage*velocitypackage+totalmassinboart*velocityboat=0
solve for velocityboat.
A child in a boat throws a 5.15-kg package out horizontally with a speed of 10.0 m/s. The mass of the child is 24.2kg and the mass of the boat is 33.2kg . Calculate the velocity of the boat immediately after, assuming it was initially at rest.
