# Question #d18ed

##### 1 Answer

The ratio of the time of flight for the two balls will be equal to **1**.

#### Explanation:

This is a great example of a trick question.

When you launch an object *horizontally* from a height **only parameter** that influences that object's time of flight is the actual height, i.e. the value of

The launch velocities have no impact on the total time of flight, they only affect the *horizontal distance* covered by the object.

The movement of the two balls has a **horizontal component** and a **vertical component**. The same can be said for the initial velocity.

When you launch a ball **horizontally**, the angle it makes with the horizontal is equal to

Since the initial velocity has no **vertical component**, the vertical displacement will be equal to

This means that you have

*for the first ball*;

*for the second ball*;

Therefore,
