In its final trip upstream to its spawning territory, a salmon jumps to the top of a waterfall 1.9m high. What is the minimum vertical velocity needed by the salmon to reach the top of the waterfall?(adsbygoogle = window.adsbygoogle || []).push({});

There seems to be some piece of information missing.

I know that:

a = 9.8 m/s^2

dy = 1.9m

I'm thinking i'll probably be using the formula (Vf^2 = Vi^2 + 2ad) so that would mean I need to have the Vf or the Vi. Would either of these be equal to zero?!

Any help is appreciated!

Thanks,
