Projectile Motion (No initial velocity)

Click For Summary
SUMMARY

The discussion focuses on calculating the minimum initial speed required for a salmon to reach a waterfall 0.55 m high from a distance of 2.00 m, with a launch angle of 32.0 degrees. The relevant equation used is \(\Delta y = v_i \sin \Theta \Delta t + \frac{1}{2} g \Delta t^2\). Participants emphasize the importance of showing work for accurate assistance and troubleshooting discrepancies between manual calculations and graphing calculator results.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with trigonometric functions in physics
  • Ability to manipulate kinematic equations
  • Experience with graphing calculators for verification

Homework Statement


A salmon starts 2.00 m from a waterfall that is 0.55 m tall and jumps at an angle of 32.0. What must be the salmon's minimum initial speed to reach the waterfall.


Homework Equations


\Deltay=visin\Theta\Deltat+1/2g\Deltat2

The Attempt at a Solution


I have tried all the related formulas for projectile motion, and I felt like I got somewhere a few times. But the results aren't really checking with a graphing calculator.
