A forklift of mass 1800 kg is moving at 6.0 m/s when a box falls into its path. The operator's reaction time is 0.60 s. Once the brakes are applied, they produce a constant resultant force of 5400 N. What is the minimum distance from the box at which the operator must first see it for the forklift to stop in time?
