SUMMARY
The problem involves calculating the horizontal velocity of a steel ball rolling off a table 1.063 meters high, landing 0.229 meters away. The time of flight was determined to be 0.4657 seconds using the equation d = 0.5at², where a is the acceleration due to gravity (9.8 m/s²). The horizontal velocity was then calculated using the formula vₓ = Δx/t, resulting in a final velocity of 0.4916 m/s. The initial calculation was confirmed correct after resolving a calculator error.
