In its final trip upstream to its spawning territory, a slamon jumps to the top of a waterfall 1.9m high. What is the minimum vertical velocity needed by the salmon at the end of this motion?

Answer 1

please, please help me answer this!

Answer 2

The exact same speed that it would have at the bottom if it fell 1.9 m instead of jumping up.
We already did a falling problem yesterday.
