1. A train of mass 15 000 kg accelerates from rest for 25 s. If the total force from the engines is 8600 N, what is the train’s final velocity?

You can find the acceleration of the train by rearranging f = ma to get a = f/m

Then you can use the appropriate suvat equation to find the final velocity given the information you have.

thank you!

Use a=f/m to get the acceleration and then v=u+at to get the final velocity. Remember u is 0 because it starts from rest. Hope this helped.
