1. stone
s=9,5m
a=g≈10m/s²
t1=?
s=(at²)/2
2s=at²
2s/a=t²
t=√(2s/a)=√(2*9.5m/10m/s²)=√(1,9s²)≈1,38s
2. sound
s=9,5m
V=343m/s²
t2=?
V=s/t
Vt=s
t=s/V=9,5m/343m/s≈0,03s
-------------------------------------------------
V1+V2=1,38s+0,03s=1,41s

Energy is lost when machines don't work right. it is false because the law of conservation of energy states that energy can not be created or destroyed (lost)

the surrounding gas a lot easier than, say, a hot batch of mud can
rise through the surrounding mud.
