A shell is fired from a cannon with a velocity 20 m//s at an angle 60^(@) with the horizontal. At the highest point it explodes into three pieces of equal masses . One of the pieces retraces its path to the cannon , the second piece moves vertically up with speed 40 m//s , the third piece will move with velocity (immediately after the explosion)

A shell is fired from a cannon with a speed of 100 m//s at an angle 60^(@) with the horizontal (positive x -direction). At the highest point of its trajectory, the shell explodes in to two equal fragments. One of the fragments moves is the speed of the other fragment at the time of explosion.
