Question

Suppose a Chinook salmon needs to jump a waterfall that is1.50 m high. If the fish starts from a distance 1.00 m from thebase of the ledge over which the waterfall flows, find the x- andy-components of the initial velocity the salmon would need to justreach the ledge at the top of its trajectory. Can the fish makethis jump? (Remember that a Chinook salmon can jump out of thewater with a speed of 6.26 m/s.) Include a diagram showing your work. Note please answer this question in the context of Relative Velocity, as it is from that section ofthe physics textbook. Thank you so much for the help, I really appreciate it!

Explanation / Answer

   in the given problem let us assume that thespeed    vaw = speed of the object in airwith respect to air          = 6.26 m/ s     vww = speed of the objectin water with respect to water    height of the fall h = 1.50 m    the requires speed va in air willbe    va = (2 g h)        = ...... m / s    as we can see that    va2 =vaw2 - vww2    vww = ......... m / s    the time taken to move d = 1.00 m willbe    t = d / vww      = ....... s    angle will be     =tan-1(va /vaw)          = .........o    the x-component of the velocity willbe    (vww)x =vww cos    the y-component of the velocity willbe    (vww)y =vww sin    the x-component of the velocity willbe    (vww)x =vww cos    the y-component of the velocity willbe    (vww)y =vww sin
