Given: The battleship and enemy ships 1 and 2 lie along a straight line. Neglect air friction. Consider the motion of the two projectiles fired at t = 0. Their initial speeds are different and they reach different maximum heights h_{1 }and h_{2}. What is the ratio of the time of flight, t _{1} and t_{2} respectively, that the shells reach?

1. t_{1} / t_{2} = 2 (√ h_{1} / h_{2})

2. t_{1} / t_{2} = 1/ √2 (√ h_{1} / h_{2})

3. t_{1} / t_{2} = 2 (√ h_{2} / h_{1})

4. t_{1} / t_{2} = 1/2 (√ h_{1} / h_{2})

5. t_{1} / t_{2} = (√ h_{1} / h_{2})

6. t_{1} / t_{2} = 1/2 (√ h_{2} / h_{1})

7. t_{1} / t_{2} = h_{2} / h_{1}

8. t_{1} / t_{2} = √2 (√ h_{1} / h_{2})

9. t_{1} / t_{2} = (√ h_{2} / h_{1})

10. t_{1} / t_{2} = (h_{1} / h_{2})
