A shell is fired from a cannon with a velocity v (m/sec.) at an angle θ with the horizontal direction. At the highest point in its path it explodes into two pieces of equal mass. One of the pieces retraces its path to the cannon and the speed (in m/sec.) of the other piece immediately after the explosion is
  • a)
    3v cos θ
  • b)
    2v cos θ
  • c)
  • d)
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A shell is fired from a cannon with a velocity v (m/sec.) at an angle ...
As one piece retraces its path, the speed of this piece just after explosion should be v cos θ
(At highest point just after explosion) NOTE THIS STEP
