Answer:
W = 100000 J = 100 KJ
Explanation:
Here we will use the most basic and general formula of work, which is as follows:
where,
W = Work Done = ?
F = Force Required = 200 N
d = Length of Track = 500 m
Therefore,
<u>W = 100000 J = 100 KJ</u>
d=235m
Alpha=35⁰
h=d×sin(alpha)=134.8m
L=d×cos(alpha)=192.5m
