A small boat is carrying four people across a river. Without any paddling, the boat moves downstream at a steady speed of 5 m/s. If the average weight of the four people is 60 kg, then what is the speed of the boat after one person gets?

Does temperature affect the dissolving phase?

In a clear, coherent, paragraph-length answer, explain why the speed of the apple half way between the release and the maximum height is not half the initial speed.
