Projectile Motion traveling particle

Click For Summary
SUMMARY

The discussion focuses on solving a projectile motion problem involving a particle traveling between two parallel vertical walls separated by 13 meters at a constant speed of 5.5 m/s. Key calculations include determining the speed of the particle upon impact with the opposing wall and the angle of incidence relative to the wall. To find the y-component of the initial velocity, participants are advised to use the inverse tangent function and to draw a diagram for clarity in identifying the correct angle. The time taken for the particle to traverse the distance between the walls is also a critical aspect of the problem.

PREREQUISITES
  • Understanding of projectile motion principles
  • Knowledge of trigonometric functions, specifically inverse tangent
  • Ability to calculate components of velocity
  • Familiarity with basic kinematic equations
NEXT STEPS

Hi, can somebody please give me hints as to how to do this problem?

A particle travels between two parallel vertical walls separated by 13m. It moves toward the opposing wall at a constant rate of 5.5 m/s. It hits the opposite wall at the same height.

a) What will be its speed when it hits the opposing wall?
b) At what angle with the wall will the particle strike?

How do I calculate delta y when the initial angle not given?

Thanks so much! :smile:

Hint: Solve for the y-component of initial velocity.
How much time does it take for the particle to travel between the walls?
 
Yes, you'll need the inverse tangent. Be sure to draw yourself a diagram so that you identify the correct angle. (Note that it asks for the angle with the wall.)
