an object was launched with the velocity of 20 m/s at an angle 45 degree to the vertical . at the top of its trajectory the object broke into two equal pieces.one piece fell vertically downward .where would the other piece fall?(g=10m/s^2)
it i'll be 60m
as there is no external force acting except gravitational force ,do its path should be at the range of parabolic path
conservation of momentum m1d1+m2d2=md
the other piece will fall 60m far from origin
