Total mechanical energy E of an object of mass m, at a height h above the ground is given by the relation
E = mgh +`p^2/(2m)`
Find the dimensions of p. (g = acceleration due to gravity).

Explanation

To find the dimensions of \( p \) in the equation for total mechanical energy \( E \), we will follow these steps:

### Step 1: Understand the equation for total mechanical energy
The total mechanical energy \( E \) is given by:
\[ E = mgh + \frac{p^2}{2m} \]
where:
