SUMMARY
The discussion focuses on calculating the speed of a boat after a child throws a 3.4 kg package horizontally at 10 m/s. Using the principle of conservation of momentum, the equation mv + mv = mv + mv is applied. The initial momentum of the system is zero, leading to the equation 0 = (3.4 kg)(10 m/s) + (20 kg + 60 kg)v. The final speed of the boat is calculated to be -0.425 m/s, indicating the boat moves in the opposite direction of the throw.
