A gun fires a bullet horizontally with a velocity of 90 m/s from a tower. Neglecting air resistance, how far will the bullet travel horizontally in 4 seconds?

The distance covered along the horizontal axis is

The distance covered along the vertical  axis is  

Explanation:

From the question we are told that  

    The horizontal velocity is  

     The time considered is  

Generally the distance which the bullet will cover in the horizontal direction for the given time is  mathematically represented as

Here a is the acceleration along the horizontal direction and the value is  

So

=>  

Generally the distance which the bullet will cover in the vertical  direction for the given time is  mathematically represented as

Here   is the initial  velocity of the bullet along the vertical axis and the value is  

=>
