```										Dear Neel
stone will go upwards  and at its maximum height its velocity will be zero
apply v2= u2 + 2as
put,v=0, u= 10, a=g=-10 m/s2
s=?
0=100-20*s
it gives s= 5m
it will cover total distance of 2*5=10m (up and down)
for calculation of time use s=ut + 0.5at2
remember s in these equtions is displacment , when stone go up and then come down total displacement will be zero.
s=0, u= 10, a=g=-10
put these values it gives t=2 sec.
