A balloon was moving upwards with a uniform velocity of $\displaystyle 10$ m/s. An object of finite mass is dropped from the balloon when it was at a height of $\displaystyle 75$ m from the ground level. The height of the balloon from the ground when object strikes the ground was around : (takes the value of $\displaystyle g$ as $\displaystyle 10 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
(1)
$\displaystyle 125$ m
