Problem

An isolated particle of mass

m

is moving in horizontal plane (

x

y

), along the

x

-axis, at a certain height above the ground. It suddenly explodes into two fragments of masses

\frac{m}{4}

and

\frac{3m}{4}

. An instant later, the smaller fragment is at

y = +15

cm. The larger fragment at this instant is at :-
