PLEASE ANSWER You are in a vehicle waiting at a railroad crossing and notice a train going by at a constant speed of 5 kph. You happen to notice that there’s no engineer driving the train and it seems to be on auto pilot. Down the track in the direction the train is traveling, you see a Humane Society van full of cute puppies and kittens stalled out on the tracks. Are the van’s passengers in trouble or not? Use Newton’s 2nd Law to explain.

Answers

Answer 1
Newton’s second law is which simply states that the rate of change of momentum of a body over time is directly proportional to the force applied. An example is baseball. If you hit the ball with small force it won’t go far or fly in the air fast rather slowly glide through the air and probably touch the ground in 5 seconds. Based on that this question isn’t able to use the 2nd law. A train with no driver to stop it that weighs tons more than a van with puppies in it will destroy and plow through the van no matter what. It doesn’t matter the speed nor how far away it is. They are in danger due to the fact there is no driver to stop the train and there is a big mass difference between the two transportation devices.
