here is the problem.
A cannon shoots a 6 lb shell straight up. It reaches its maximum height, 1024 feet, and splits into two pieces, 2 lb and 4 lb. The two pieces are observed to strike the ground simultaneously. The 4 lb piece hits the ground 1600 feet away from the explosion(measured along the x AXIS)
a. How long would it have taken the shell to return to the ground if it had not split?
I found the TIME=8 seconds.
b.Find the velocity of each of the two pieces just after the explosion.
2lb piece - 400 ft/s
4lb piece - 200ft/s
AND PART "C" is where I get stuck! PLEASE HELP HERE.
Here is part "C"
c. Find the momentum of each piece just before they strike the ground.WHAT SHOULD I DO.
Please Help
The answer in the book is
2lb piece - p(vector) = -25i(unit vector)x - 16i(unit vector)z
4lb piece - p(vector) = 25i(unit vector)x - 32i(unit vector)z
