A gun fired a shell which came out of the barrel with velocity of 500 m/s at an
angle of 300 with the horizontal. This shell exploded in to two equal pieces A and B.
out of these two pieces A fell down just below the highest point . The mass of the
shell fired from the gun is 20 Kg.
Now answer the following question:
(i) The path followed by the centre of mass of the shell is 1
(a) Straight (b) parabolic (c) hyperbolic (d) circular
(ii) the centre of mass of two fragment taken together compared to that of the shell
before explosion,shifts towards 1
(a) The piece which fell down just below the highest point.
(b) The other piece.
(c) Does not shift.
(d) None of these.
(iii) The velocity of the piece A after 10 seconds is 2
(a) 9.8 m/s (b) 98 m/s (c) 49 m/s (d) 0.98 m/
