intial velocity = u = 49 
final velocity = v = 0
 acceleration =  a = 9.8
s = height 
v²-u² = 2 a s

Final velocity(v)=49 metre per second
initial velocity(u)=0
g=9.8 metre per second²
h=?
v²=u²+2gh
⇒v²=2gh
⇒h=v²÷2g
⇒h=49×49/9.8×2
⇒h=122.4999999 metres
Hence, the maximum height reached will be 122.4999999 metres.
