Baseball Player Hits Home Run: Calculating Velocity and Flight Time

Click For Summary
SUMMARY

The discussion focuses on calculating the initial velocity and total flight time of a baseball hit at a 35-degree angle, clearing a height of 21 meters and traveling a horizontal distance of 130 meters. Participants emphasize the importance of using kinematic equations to derive the initial velocity components (vx0 and vy0) and to determine the total flight time. The conversation highlights the necessity of showing work in calculations to facilitate understanding and assistance.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with kinematic equations
  • Basic trigonometry for angle calculations
  • Knowledge of initial velocity components in physics
NEXT STEPS
  • Study the kinematic equations for projectile motion
  • Learn how to resolve vectors into horizontal and vertical components
  • Explore the concept of maximum height in projectile motion
  • Research the effects of air resistance on projectile trajectories
USEFUL FOR

Students studying physics, educators teaching projectile motion, and sports analysts interested in the mechanics of baseball hits.

a baseball player hits a home run that just clears the top of the bleachers 21m high located
130m from home base. the ball is hit at an angle of 35* above the horizontal

a) find initial velocity of the ball

b)the total time of the flight of the ball...

Hi dralion87! :smile:

Well, you know x1 y1 and vx0/vy0.

So what equations can you use? :smile:
