To find the work done, we can use the formula for work, which is:
\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]
where:
- \( \text{Force} \) is the applied force (in Newtons),
- \( \text{Distance} \) is the distance over which the force is applied (in meters),
- \( \theta \) is the angle between the force and the direction of movement.
In this case, the force is applied parallel to the ramp. We'll assume that the force applied is in the same direction as the displacement, so \( \theta = 0^\circ \) and \( \cos(0^\circ) = 1\).
Given:
- Force = 98 N
- Distance (along the ramp) = 4 m
Using the formula for work:
\[ \text{Work} = 98 , \text{N} \times 4 , \text{m} \times 1 = 392 , \text{Joules} \]
Therefore, the work done is 392 Joules.
