SUMMARY

The discussion focuses on calculating the launch angle of a lob pass thrown at an initial speed of 21.5 m/s with a time of flight of 2.97 seconds, and determining the initial speed and time of flight for a bullet pass thrown at a launch angle of 25 degrees. The kinematic equations of motion are essential for solving these problems. Specifically, the equations relate initial speed, launch angle, time of flight, and gravitational acceleration. Participants emphasize the importance of applying these equations correctly to derive the necessary values.

PREREQUISITES
  • Kinematic equations of motion
  • Understanding of projectile motion
  • Basic trigonometry for angle calculations
  • Knowledge of gravitational acceleration (9.81 m/s²)
NEXT STEPS
  • Study the derivation of kinematic equations of motion
  • Learn how to calculate projectile motion parameters
  • Explore the impact of launch angle on projectile distance
  • Practice solving problems involving different launch angles and speeds
USEFUL FOR

Physics students, sports coaches, and anyone interested in understanding the mechanics of projectile motion and optimizing pass techniques in sports.

the lob pass is thrown with an initial speed of 21.5 m/s and its time of flight is 2.97s. What is its launch angle?

The bullet pass is thrown with a launch angle of 25 degrees. What is the initial speed of this pass? What is the time of fight of the bullet pass?

what formulas and how is this worked out?

Welcome to the PF. You use the kinematic equations of motion, which you no doubt are studying now. What are those equations? How would you use them to start to solve these problems?
