Adog leaps horizontally off a 70 m cliff with a speed of 6 m/s, how far from the base will the dog land?

Explanation:

Let's use projectile motion equations. First of all we need to find the travel time. So we are going to use the next equation:

(1)

Where:

In this case:

Because the dog jumps horizontally

Let's asume the gravity constant as:

Because when the dog reach the base the height is 0

Now let's replace the data in (1)

Isolating t:

Finally let's find the horizontal displacement using this equation:

Replacing the data:
