SUMMARY

The angular displacement of a ball with a radius of 0.260 m rolling off a table at a linear speed of 3.00 m/s can be calculated using the time it takes to fall a vertical distance of 2.30 m. The time in the air is determined using the equation for free fall, resulting in approximately 0.68 seconds. During this time, the ball maintains a constant angular velocity, which can be calculated as 11.54 rad/s. The total angular displacement while in the air is approximately 7.83 radians.

PREREQUISITES
  • Understanding of angular displacement and angular velocity
  • Basic principles of projectile motion
  • Knowledge of kinematic equations for free fall
  • Familiarity with the relationship between linear and angular motion
NEXT STEPS
  • Calculate angular displacement for different rolling objects
  • Explore the effects of varying radius on angular velocity
  • Investigate the relationship between linear speed and time of flight in projectile motion
  • Learn about the conservation of energy in rolling motion
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of rolling motion and projectile motion in real-world applications.

A ball of radius 0.260 m rolls along a horizontal table top with a constant linear speed of 3.00 m/s. The ball rolls off the edge and falls a vertical distance of 2.30 m before hitting the floor. What is the angular displacement of the ball while it is in the air? (assume that there is no slipping of the surfaces in contact during the rolling motion.)

What's the angular velocity of the ball? (You can calculate this, because you know its linear speed and radius).

What is the amount of time the ball is in the air?

Show us what you have done.
 
Also note that only the vertical speed changes while the ball is falling, not the horizontal speed or angular velocity.
