Suppose a Chinook salmon needs to jump a waterfall that is 1.45 m high. If the fish starts from a distance 1.02 m from the base of the ledge over which the waterfall flows, find the x- and y-components of the initial velocity the salmon would need to just reach the ledge at the top of its trajectory.
v0x = __ m/s
v0y = __ m/s
Can the fish make this jump? (Assume that a Chinook salmon can jump out of the water with a speed of 6.26 m/s.)
Thank you so much in advance! :) Any help would be great! I only have a few guesses left before I get the answer wrong.

Worry about the vertical component first. Use s = 0.5 g t^2 to calculate the time required, and v = g t to get the required velocity. The horizontal velocity will be the time divided by the horizontal distance. The velocity components are at right angles, so use Pythagoras to get the total velocity.

Why yes, as a matter of fact, I do understand physics âº
And didn't I (and someone else) both just answer this same question?
Or are you so scatterbrained that you've forgotten that you already asked?
