An isolated particle of mass m is moving in a horizontal plane (x-y), along the x-axis at a certain height above the ground. It suddenly explodes into two fragments of masses m//4 and 3m//4 . At instant later, the smaller fragment is at y = +5 cm . What is the position of larger fragment at this instant ?
