The time required for the sphere to fall from the table edge to the floor depends exclusively on: Experiment Context (Incline Ramp Velocity and Range): A steel sphere (mass = 0.05 kg) was released from rest at various heights (h) above a smooth table, rolling down a ramp and launching horizontally from a table height of 1.0 m: Table 3: - h = 0.10 m: Launch speed = 1.4 m/s; Horizontal range = 0.63 m - h = 0.20 m: Launch speed = 2.0 m/s; Horizontal range = 0.90 m - h = 0.40 m: Launch speed = 2.8 m/s; Horizontal range = 1.27 m - h = 0.80 m: Launch speed = 4.0 m/s; Horizontal range = 1.81 m
