Calculate the work done by a car against gravity in moving along a straight horizontal road. The mass of the car is 400 kg and the distance moved is 2m.

Explanation

To calculate the work done by a car against gravity while moving along a straight horizontal road, we can follow these steps:

### Step 1: Identify the Forces Involved
The main force acting against gravity is the weight of the car, which can be calculated using the formula:
\[ F = mg \]
where:
- \( m \) is the mass of the car (400 kg)
- \( g \) is the acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \))
