I think the answer is c but I’m not sure
Answer:
Distance = 10m
Imagine a triangle
Length = 4 - 1 = 3
Height = 2 + 2 =4
Hypothenuse = Displacement
Displacement = 5
Work = force x distance.
force = mass x acceleration
work = mass x acceleration x diastance
use acceleration of gravity in this problem
W (J) = m (kg) x a (m/s/s) x d (m)
W = 78 x 9.8 x 6
W = 4586.4
