Answer 3

hint:
I suppose that the motion of your flowerpot is a vertical motion.
Time needed to flowerpot to reach the earth surface is:
\[\Large \frac{{{v_0}}}{g}\left\{ {1 + \sqrt {\frac{1}{2} + \frac{{2g{h_0}}}{{v_0^2}}} } \right\}\]
where v0= 1m/sec and h0 is the maximum height reached by our flowerpot
the final speed of our flowerpot, is:
\[\Large \sqrt {2g{h_0} + v_0^2} \]
Please use those information, and you will get your answers
