Projectile Motion Homework: Calculating Net Height for Daredevil Cannon Launch

Click For Summary

Homework Help Overview

The problem involves projectile motion, specifically calculating the height at which a net should be placed to catch a daredevil launched from a cannon at a 45-degree angle with a given initial speed. The scenario includes parameters such as horizontal distance and initial velocity.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to use a specific equation related to projectile motion but indicates that it did not yield the expected result. Another participant suggests a different equation for calculating the height based on projectile motion principles.

Discussion Status

The discussion is ongoing, with participants exploring different equations and approaches to the problem. There is a request for clarification on the original poster's attempt, indicating a desire for deeper understanding rather than a straightforward solution.

Contextual Notes

The original poster mentions an expected answer, which may influence the assumptions being made about the problem setup. There is also a note about a complete solution being removed, which may affect the flow of the discussion.

Homework Statement


A daredevil is shot out of a cannon at 45degrees horizontal with an initial speed of 25.0m/s. A net is positioned at a horizontal distance of 50m from the cannon from which it is shot. At what height above the cannon should the net be placed in order to catch the daredevil?


Homework Equations



P=X/ViCos(theta)


The Attempt at a Solution


i tried this equation but it did not work out. The answer is supposed to be 10.8m. Please explain it if you get this correct. Thank you!
