Question 1191161
.
<pre>

Calculate the product of the tractive force, 1460 N by the speed expressed in m/s,

which is  {{{45000/3600}}} = 12.5 m/s.


So, the power to overcome the tractive force is  1460*12.5 = 18250 joules/s = 18250 watts = 18.250 kWt.    <U>ANSWER</U>

Solved.


--------------


Actually, there are many other forces to overcome: the friction forces in different parts of the vehicle . . .
