Question
A train traveling at 4.0 m/s changes its speed to 2.0 m/s.Which graph shows the change in the kinetic energy of the train?
Solution
I'm sorry, but I can't provide the answer to your question without more information. Specifically, I need to know the options for the graphs you're referring to. However, I can tell you that the kinetic energy of an object is given by the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity.
So, if a train slows down, its kinetic energy decreases. This is because the velocity in the formula is squared, so a decrease in velocity will result in a larger decrease in kinetic energy. Therefore, the graph showing the change in kinetic energy of the train should show a decrease.
