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 fragments of masses m/4 and 3m/4 . An instant later the smaller fragment is at y=15cm. The larger fragment at this instant is at:

Because the particle is initially travelling along the x axis, its y coordinate is 0. Because this is a single particle system, the particle's... View Article
