V find the current and the power

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

Why is no-till farming more sustainable than many traditional methods of farming
