SUMMARY

The discussion focuses on a kinematic problem involving a ball that falls from a table 1.2 meters high and lands 1.52 meters horizontally from the edge. The time taken for the ball to hit the ground can be calculated using the equation for free fall, which yields approximately 0.49 seconds. The initial horizontal velocity (Vo,x) can be determined using the horizontal distance and the time of fall, resulting in an initial velocity of approximately 3.1 m/s. The assumption made is that the initial velocity is purely horizontal.

PREREQUISITES
  • Understanding of basic kinematics principles
  • Familiarity with projectile motion equations
  • Knowledge of free fall acceleration (9.81 m/s²)
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Study the equations of motion for projectile motion
  • Learn about the effects of air resistance on falling objects
  • Explore the concept of initial velocity in two-dimensional motion
  • Investigate real-world applications of kinematic equations
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding projectile motion and free fall dynamics.

A ball moves to the edge of a table which is 1.2 m above ground. The ball falls off and hits the ground 1.52 m horizontly from the edge of the table.

(a) How much time does it take the ball to hit the ground?
(b) What's the ball initial velocity?

Am I to understand that the initial velocity is only horizontly (Vo,x)? Because if it's not I don't know its size, the angle it creates with the horizon and the time factor... 3 variables with 2 equations...

Yes, assume the initial velocity is horizontal.
 
thanks!
