A covering is shot with an early stage velocity
The ideas used to deal with this difficulty are projectile motion and the law of preservation of momentum.
You are watching: A shell is shot with an initial velocity
Initially, usage the expression in terms of initial velocity and the edge made by the early stage velocity with the horizontal to determine the horizontal component of the early stage velocity the the shell.
Finally, usage the regulation of conservation of momentum to recognize the speed of 2nd fragment instantly after the explosion.
The horizontal ingredient of the early stage velocity in a projectile activity is offered as follows:
Here, the horizontal ingredient of the early velocity is
According come the law of conservation of momentum, “the total momentum of one isolated system remains the same”.
The inert of a human body is offered by the expression together follows:
Here, the inert is
The horizontal ingredient of the early stage velocity in a projectile movement is given as follows:
According to the legislation of preservation of momentum, “the total momentum of an isolated mechanism remains the same”.
The initial momentum of the covering at the top of the trajectory prior to explosion is provided as follows:
Here, the initial momentum is
The shell explodes right into two pieces of same mass at the peak of the trajectory.
The masses that the two fragments will be half of the fixed of the shell.
Here, the fixed of the first and second fragments room

The last momentum at the height of the trajectory ~ explosion is given as follows:
Here, the final momentum is
