Description: A light train made up of two cars is traveling at 90 km / h when the brakes are applied to both cars. Knowing that car A has a mass of 25 Mg and car B a mass of 20 Mg , and that the braking force is 30 kN on each car, determine (a) the distance traveled by the train before it comes to a stop, (b) the force in the coupling between the cars while the train is slowing down.

step 1 four guests. Okay, We apply Newton's law in the horizontal direction. That is, the sum of forces

Question

A light train made up of two cars is traveling at $90 \mathrm{~km} / \mathrm{h}$ when the brakes are applied to both cars. Knowing that car A has a mass of 25 Mg and car $B$ a mass of 20 Mg , and that the braking force is 30 kN on each car, determine (a) the distance traveled by the train before it comes to a stop, (b) the force in the coupling between the cars while the train is slowing down.

Step 1

Step 1: Let's identify the given information: - Initial velocity of the train: v₀ = 90 km/h = 90 × (1000/3600) = 25 m/s - Mass of car A: mₐ = 25 Mg = 25,000 kg - Mass of car B: mᵦ = 20 Mg = 20,000 kg - Braking force on each car: F = 30 kN = 30,000 N Show more…
