How High Can a Salmon Jump if It Leaps at 2.5 Meters Per Second?

AI Thread Summary
To determine how high a salmon can jump when it leaps at 2.5 meters per second, one can apply the equations of motion and consider gravitational acceleration at 9.81 m/s². The relevant formulas include V final = V initial + A(t) and X final = X initial + V initial (t) + 1/2A(t²). It's suggested to also approach the problem using conservation of energy, where the kinetic energy of the salmon converts into potential energy during its jump. By calculating the maximum height using these principles, one can find the answer to the question. Understanding these equations is essential for solving similar physics problems.

Homework Statement


If a salmon swims straight upward in the water fast enough to break through the surface at a speed of 2.5 meters per second, how high can it jump above water?


Homework Equations


i don't know, because all i know is speed.



The Attempt at a Solution


is acceleration 9.81 in this? i don't know how to figure it out : [
 
Physics news on Phys.org


the formulas you need are:

V final = V initial + A(t)

and

X final = X initial + V initial (t) + 1/2A(t^2)

where x is distance, v is velocity and a is acceleration (yes, 9.81 m/s^2)

write'em down, I'm sure they're in your book, and should get you started on all your problems.
 


You may as well approach the question from the conservation of energy side. Kinetic energy gest converted into potential during flight.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
