A ball is rolled horizontally off a table with an initial speed of 0.18 m/s.A stopwatch measures the ball's trajectory time from table to the floor to be 0.30 s.How far away from the table does the ball land? Note: g = 9.8 m/s² and air resistance is negligible. A) 0.054 m B) 0.072 m C) 1.2 m D) 1.9 m

The correct answer is A because the ball's horizontal velocity is constant, and the vertical velocity is due to gravity. The horizontal distance traveled is equal to the initial horizontal velocity multiplied by the time of flight. The time of flight is equal to the vertical distance traveled divided by the vertical velocity. The vertical distance traveled is equal to half the acceleration due to gravity multiplied by the time of flight squared.
