Work is defined as the product of force and the distance over which that force is applied, and is given by the formula:
\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]
where \( \theta \) is the angle between the force and the direction of movement. In this case, since Mark was unable to move the car, the distance it moved is zero.
Therefore, regardless of the force he applied:
\[ \text{Work} = 9000 , \text{N} \times 0 , \text{m} \times \cos(0) = 0 , \text{J} \]
Thus, the amount of work done by Mark is \( 0 , \text{J} \) (joules).
