What is the minimum speed must a salmon jumping at an angle of 35.2 leave the water in m/s?

Height of the waterfall is 0.449 m

its horizontal distance will be 2.1 m

now let say his speed is v with which he jumped out so here the two components of his velocity will be

here the acceleration due to gravity is 9.81 m/s^2 downwards

now we can find the time to reach the other end by y direction displacement equation

also from x direction we can say

now we have

we will plug in this value into first equation

now as we know that

t = 0.63 s

so his minimum speed of jump is 4.1 m/s

answer: he got 23

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
