denote the initial speed of a cannon ball fired from a battleship as Vo. when the initial projectile angle is 45 degrees with respect to the horizontal, it gives a maximum range of R.
the time of flight of the cannonball for this maximum range R is given by
1.t=(1/3^1/2)vo/g
2.t=3^1/2(vo/g)
3.t=2^1/2(vo/g)
4.t=2(vo/g)
5.t=1/2(vo/g)
6.1/(2^1/2)(vo/g)
7.t=4(vo/g)
8.t=(1/4)(vo/g)
9.t=(2/3)(vo/g)
the time of flight of the cannonball for this maximum range R is given by
1.t=(1/3^1/2)vo/g
2.t=3^1/2(vo/g)
3.t=2^1/2(vo/g)
4.t=2(vo/g)
5.t=1/2(vo/g)
6.1/(2^1/2)(vo/g)
7.t=4(vo/g)
8.t=(1/4)(vo/g)
9.t=(2/3)(vo/g)
