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.
