The engines are turned off so there is no tractive force. The train is moving at 20 mph down the incline. What is the required magnitude of the braking force to bring the train to a stop in 1670 ft? (include units with answer)

the body's situation won't change the forces are equal opposit and on the same body

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
