Warren's Cannonball Launch Velocity?

Click For Summary

Homework Help Overview

The problem involves a scenario where Warren, weighing 70 kg, is launched from a cannon at an angle of 25 degrees above the horizontal. The cannon barrel is positioned 1.34 meters above the ground, and the cannon itself has a mass of 203 kg. The primary question is to determine Warren's initial launch velocity.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants express uncertainty about the completeness of the problem, questioning whether additional information is needed to solve for the initial launch velocity. Some participants inquire about relevant equations and their applicability to the problem.

Discussion Status

There is an ongoing exploration of the problem's requirements, with participants discussing the potential absence of necessary information, such as the range of the projectile. Some guidance has been offered regarding the identification of relevant equations, though no consensus has been reached on how to proceed with the solution.

Contextual Notes

One participant noted that their professor indicated the problem was missing the range, which may be critical for determining the initial launch velocity. This suggests that the problem may not be fully defined as presented.

Homework Statement


Warren weights 70 kg and is shot out of a cannon at 25 degrees above the horizontal. the cannon barrel tip is 1.34m above the ground and the cannon has a mass of 203kg.
What is Warren's initial launch velocity?

Homework Equations


I don't even know

The Attempt at a Solution


I think that this problem is missing some info, or I'm really bad at physics

Doesn't your textbook give you a list of equations for whatever you're learning?

We don't go by the textbook, she teaches us with labs and stuff, there are several equations but none of them fit

Also this is review for my final and we learned it a while back, I'm taking a practice test and need to get this question right
 
Post the equations that you do know.

d = vi•t + 0.5*a*t2
vf = vi + a•t
vf2 = vi2 + 2*a•d
that's about it, i can't find a lot of formulas pertaining to initial launch velocity

What happens to Warren after he leaves the cannon? Without knowing that, you can't determine what Warren's initial launch velocity was.

What numbers in your problem matches the variables in those equations?

If that is the complete problem statement, the problem does not make sense.
Is there something else given? Maybe in a second part, or in a sketch of the problem?

Guys, I went to my professor and she said that it was missing the range, sorry for sounding really confusing.
