How far will an object move in 3 s if its average speed during that time is 40 m/s? answer in units of m.

What is the most useful equation for electric power?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

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,?
