Question 1090198
.
A ball thrown vertically upwards at  1.2 m/s  and decelerates uniformly at  10  {{{highlight(cross(m/s))}}}  {{{m/s^2}}}.  How long till zero velocity ?
~~~~~~~~~~~~~~~~~~~~~~~


If you know the beginnings of Mechanics (as a part of Physics),  then you know that

<pre>
   at the uniformly decelerated motion,  time to get zero velocity is  {{{V[0]/g}}} = {{{1.2/10}}} = 0.12  seconds.
