Physics

A cannon shoots a shell straight up. It reaches its maximum height, 1,051 feet, and splits into two pieces, one weighing 2 lb and the other 4 lb. The two pieces are observed to strike the ground simultaneously. The 4 lb piece hist the ground 1,608 feet away from the explosion (measured along the x axis). How long would it have taken the shell to return to the ground if it has not split? (answer to two decimal points)
