Question

A toy train has an engine that weighs 150 grams. It is coupled to a car with a mass of 30 grams. The coupling between the engine and the car is a magnet with a maximum attractive force of 0.9 Newtons. What is the maximum pulling force that can be done by the engine to avoid the car separating from it? Neglect the mass and friction associated with the wheels of the toy

a-toy-train-has-magnetic-couplers-whose-maximum-attractive-force-is-02-lb-between-adjacent-cars-what

A toy train has magnetic couplers whose maximum attractive force is 0.2 lb between adjacent cars. What is the maximum force $P$ with which a child can pull the locomotive and not break the train apart at a coupler? If $P$ is slightly exceeded, which coupler fails? Neglect the mass and friction associated with all wheels.

A freight train consists of 3 engines at the front, followed by 22 rail cars. Both the engines and rail cars have the same mass of 664,138 kilograms each. Each engine exerts the same force backward on the track to push the train forward. The total force of friction on the entire train is 698,823 Newtons and is evenly distributed among all of the cars and engines. Even with this friction present, the train engines are able to accelerate the train at 0.039 meters/second^2. What is the magnitude of the force in Newtons in the coupling between the engine and the first rail car?

A freight train consists of 5 engines at the front, followed by 33 rail cars. Both the engines and rail cars have the same mass of 574,641 kilograms each. Each engine exerts the same force backward on the track to push the train forward. The total force of friction on the entire train is 560,914 N and is evenly distributed among all of the cars and engines. Even with this friction present, the train engines are able to accelerate the train at 0.058 meters/second^2. What is the magnitude of the force in Newtons that each engine would need to exert on the train track?

00:01 Here in this question we have weight of an engine equals to 150 gram which can be written as 0 .150 kilogram.
00:25 Also we have mass of box equals to 30 gram which can be written as 0 .150 kilogram which can be written as 0 .10 kilogram.
00:43 0 .030 kilogram and we have attractive force between engine and box car equals to 0 .9 newton.
01:11 Now we are going to calculate the maximum force that the engine could generate to avoid the box car from separating from it.
01:21 So first of all we need to determine acceleration of the train.
01:29 So from newton's second law we have f equals to m of e plus m of b multiply by a...
