What is work done in holding a 15kg suitcase while waiting for a bus for 15 minutes ?

Explanation

To solve the problem of calculating the work done in holding a 15 kg suitcase while waiting for a bus for 15 minutes, we can follow these steps:

### Step 1: Understand the concept of work done
Work done (W) is defined as the product of the force (F) applied and the displacement (S) in the direction of the force. Mathematically, it is expressed as:
\[ W = F \cdot S = F \cdot S \cdot \cos(\theta) \]
where \( \theta \) is the angle between the force and the direction of displacement.

### Step 2: Identify the forces acting on the suitcase
