Answer:
The work is defined by the product of force and displacement. Its standard formula is,
W = F.d.Cos\alpha
Here F is force, d is displacement and α is angle subtended by force from horizontal.
As given in the question,
F = 255N, d = 30m, α = 30°
On putting in the above formula
W = 255×30×Cos30°
=7650×0.906
= 6930.9 J

Answer: 6117.58 J
Explanation:
We know that W=Fd*cos(theta) where theta is the angle between the displacement and the force.
In this case, we are given that F=225 N, d=30 m, and theta=25 degrees.
Plugging all this in we get
W=225*30*cos(25)=6117.58 J
