Question

The dynamic brakes will NOT start to function until the train has reached a speed of _____ MPH.

1) 24
2) 25
3) 50
4) 100

Answer 1

The dynamic brakes will not start to function until the train has reached a speed of 25 MPH.

Step-by-step explanation:

The dynamic brakes will NOT start to function until the train has reached a speed of 25 MPH.

Dynamic brakes are used in trains to slow down or stop the train by converting the kinetic energy of the moving train into electrical energy. They are typically activated when the train is moving at higher speeds. Once activated, the dynamic brakes help reduce the speed of the train.

For example, if a train is traveling at 50 mph and the dynamic brakes are engaged, the train will start to slow down because the dynamic brakes are converting some of its kinetic energy into electrical energy, which helps reduce its speed.
