A monkey sitting on a branch of a tree 20 m high drops a mango directly above the head of a boy as he runs with a speed of `1.5 ms^(–1)` under the tree. How far behind the boy, does the mango hit the ground?

Explanation

To solve the problem of how far behind the boy the mango hits the ground, we can break it down into a few steps:

### Step 1: Determine the time taken for the mango to fall.
The mango is dropped from a height of 20 meters. We can use the equation of motion for free fall:

\[ s = ut + \frac{1}{2} a t^2 \]
