Answer:
Position of heavy mass after t = 5 s is given as
Explanation:
Here we know that body explodes due to its internal forces
so there is no external force on it
and hence its COM will always move with same speed in same direction
so position of center of mass after t = 5 s is given as
x = 2
now we have
so we have
so position of heavy part is given as
