Answer;

a) 5.00 x 10^8 J

Explanation;

The work done to move the sailboat is calculated through the equation;

W = F x d

where F is force and d is the distance.

Substituting the known values from the given above,

W = (5.00 x 10⁴ N) (10 km) (1000 m / 1km)

= 5.00 x 10⁸ J

Thus, the work done is 5.00 x 10⁸Joules
