Beer mug across counter direction of mugs velocity

Click For Summary
SUMMARY

The discussion focuses on calculating the initial velocity of a beer mug sliding off a counter and determining its velocity direction just before impact. The formula derived for the initial velocity is Vinitial = d/sqrt(2h/g), where d is the horizontal distance from the counter base, h is the height of the counter, and g is the acceleration due to gravity. Participants emphasize the importance of breaking the motion into components to analyze the velocity direction effectively just before the mug strikes the floor.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with kinematic equations
  • Basic knowledge of vector components
  • Concept of gravitational acceleration (g = 9.81 m/s²)
NEXT STEPS
  • Study the derivation of projectile motion equations
  • Learn about vector decomposition in physics
  • Explore the effects of initial velocity on projectile trajectories
  • Investigate real-world applications of projectile motion in sports
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of motion and projectile analysis in real-life scenarios.

Homework Statement


In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slides off the counter and strikes the floor at distance d from the base of the counter. The height of the counter is h. With what speed did the mug leave the counter? Which I got Vinitial=d/sqrroot(2h/g). Now my question is what was the direction of the mugs velocity just before it hit the floor?


Homework Equations





The Attempt at a Solution


Would I have to break something up into components?

Splitting it into perpendicular components seems like an excellent idea :approve:.
 
hmmm, how did you get that equation for Vinitial? i am trying to sift through all these formulas and i just can't seem to get the correct one. :confused:
