A shell is fired from a cannon with a velocity v (m/s) 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 (m/s) of the other piece immediately after the explosion is
- 3 v cosθ
- 2 v cosθ
- \(\frac{3}{2} \mathrm{v} \cos \theta\)
- \(\sqrt{\frac{3}{2}} \mathrm{v} \cos \theta\)
Answer
(A) 3 v cosθ
