I would say downstream since the stream can push your boat, then you would have momentum and would just have to row towards the land.
In gases, temperature relates to its kinetic energy — the hotter the gas, the faster the particles will move (for example, if we take that the formula of kinetic energy is Ek = 3/2 * k * T where k iz Boltzmanns constant and T is temperature, we see that kinetic energy — which is the energy an object has when its moving — only really depends on the temperature.)
Explanation:
Assuming no air resistance, the horizontal acceleration at all points is 0, and the vertical acceleration at all points is -g (if near the surface of the Earth, -9.8 m/s²).
Because almost all of the force is done by the weight of the person and the mechanism of the swing itself, when you push someone you only give them an increase in velocity, the acceleration comes from the weight at first and then from gravity when the person is coming down, which is why we bend our legs when coming down
