Work is defined as the force times the distance which is mathematically expressed W = Fxd. The given force is 5x10^4 and the distance is 10000 m (the distance is converted as meter because Nm = J) the work done by the wind is W = 5x10^4 N (10000) = 500 x 10^6 Joules. I hope it answered your question
Given,
As we know that slope of any line passing from (x,y) point has the slope as i.e. Tan
Vector's Direction can be calculated by = Tan⁻¹ ,
where is the angle with the horizontal X-axis.
therefore,
= Tan⁻¹
= 23.375°
The vector's direction is the angle that the vector makes with the horizontal axis, i.e. with the X-axis. The direction of the vector is given by turning the angle of the vector around its tail to the east counterclockwise.
Therefore, the vector's direction for the given vector is 23.375° from the X-axis i.e. the vector Ax = 26 m/s2, Ay= 10 m/s2 points towards the North-East direction.

To solve this exercise it is necessary to apply the equations concerning Work, both by general definition and by conservation of energy.
In other words, the work done by an object due to gravity is the equivalent to that defined by the potential energy equations, that is
Where,
m=mass
g=gravitational acceleration
Change in height
On the other hand we have that the work done by tension is defined by the conservation of kinetic and potential energy, that is to say
Where,
Change in Kinetic Energy
Change in Potential Energy
PART A) As defined by the work done by gravity would be given by,
Therefore the work done by gravity is 25.725kJ
PART B) The work done by the tension applies the energy conservation equation, that is to say
Replacing with our values,
Therefore the work done by tension is 25.9kJ
As weight =w =mg
g= gravitational acceleration on mercury = 3.7m/sec2
Mass of person =m= 70 kg
So w =(70kg)(3.7m/sec2)
w= 259 kgm/sec2
W= 259 N
