An 20 kg ice boat is coasting on a frozen lake with a speed of 4 m/s. Friction between the ice and the boat is negligible, and so is air resistance. Nothing is propelling the boat. A 60 kg clown drops straight down from a bridge into the boat, which continues to coast straight ahead. What is the final speed of the ice boat? (Hint: Momentum is alona the Y-axis hut not along the y-axis.)

Question

answer is vf= 1.0 m/s.

An 20 kg ice boat is coasting on a frozen lake with a speed of 4 m/s. Friction between the ice and the boat is negligible, and so is air resistance. Nothing is propelling the boat. A 60 kg clown drops straight down from a bridge into the boat, which continues to coast straight ahead. What is the final speed of the ice boat? (Hint: Momentum is conserved along the x-axis, but not along the y-axis.)
