0.65 Meter

Explanation:

We know from conservation of energy that ,

E_p=E_k
where,
E_p is potential energy
E_k is kinetic energy

similarly we can state from the above theorem that
mgh=1/2mv^2
It can be also written as
mgh=DeltaE_k

from above mentioned details we can conclude that

DeltaE_k=440-210=230J
and so we substitue in the above equation we get
mgh=230

10*35*h=230
upon solving it we get 0.65 M
