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.(adsbygoogle = window.adsbygoogle || []).push({});

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)
