SUMMARY

The discussion centers on the projectile motion of an apple core thrown from a height of 4.0 meters with an initial velocity of 5.0 m/s at an angle of 35 degrees above the horizontal. The time taken for the apple core to hit the ground is calculated using kinematic equations, resulting in approximately 1.0 seconds. The horizontal distance from the base of the tree to the landing point is determined to be around 4.0 meters. The final velocity of the apple core upon impact is computed to be approximately 10.3 m/s, considering both horizontal and vertical components of motion.

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Knowledge of vector decomposition for projectile motion
  • Familiarity with basic trigonometry
  • Ability to perform calculations involving gravitational acceleration (9.81 m/s²)
NEXT STEPS
  • Study kinematic equations for projectile motion in detail
  • Learn about vector decomposition and its application in physics problems
  • Explore the effects of air resistance on projectile motion
  • Investigate real-world applications of projectile motion in sports and engineering
USEFUL FOR

Students studying physics, educators teaching projectile motion concepts, and anyone interested in understanding the dynamics of objects in motion.

A child sitting in a tree throws his apple core from where he is perched (4.0 m high) with a velocity of 5.0 m/s [35o above the horizontal], and it hits the ground right next to his friend.
a) How long is it before the apple core hits the ground?
b) How far from the base of the tree will the apple core land?
c) What is the velocity of the apple core on impact?
