-0.930 m/s is the velocity of the boat.
<h3>Given:</h3>Mass of child and boat , = (25.0 + 38.4 )kg
= 63.4 kg
Mass of the package, = 5.90 kg
Velocity of package thrown from boat , = 10.0m/s
Initial velocity v = 0 m/s
As the boat is at rest,
According, to the law of conversation of momentum;
∴ Momentum before = Momentum after
Negative direction shows the velocity in the direction opposite to the motion of the package.
Therefore, -0.930 m/s is the velocity of the boat.
