is mathematically given by


1) 20 min = 1/3 h
2) distance = speed * time = 12 * 1/3 = 4 km
1. $85047
2. $113,080
3. $ 75,820
4. $41595
Answer:
W = 112.76MJ
Explanation:
the work is:

where
is the force executed in the direction of the displacement and the d the displacement.
so:
W = 12000Ncos(20)(10000)
we use the cos of the angule because it give us the proyection in the axis x of the force, that means the force in the direction of the displacement.
W = 112.76MJ
