Stop Train

A train engineer has neglected his duties and allows his train to slide down a hill and it is headed towards a randomly generated 'cute cliche' which could be a teddy bear orphanage, a basket of puppies warehouse or a baby seal condo. You are the watchful railyard switchman and it is up to you to stop the train. Fortunately, you have paid attention in physics classes, which allows yo u to come up with the following plan: accelerate a railcar to a speed that can catch and couple with the engine and after that slow both of them down through weight and friction. It is all simple physics. To do this, while in the car loading section you load the car with weight to increase its mass. Press and hold the space bar to open the hopper and load mass. You only have twenty seconds before the train arrives so decide how much mass should be added to the car. Next come the train catch sequence. You will see a power meter and you need to press space bar when the power meter reaches the desired level. You need to accelerate the rail car to a speed that's just right to catch and couple with the engine. If the car is too slow, it will never catches the engine. If the car is too fast, it will bounces off the engine. good luck!
