Will it take longer for a train or a car traveling at 100 mi hr to stop?

A train will generally take longer to stop than a car traveling at 100 mph due to its larger mass and the principles of momentum and braking distance. Trains require a longer distance to come to a complete halt because they rely on friction from the tracks and cannot stop as quickly as a lighter vehicle like a car. Factors such as track conditions, train type, and braking systems also influence stopping distances.
