Both options 5 and 6
Explanation:
Let us consider option 5,
In option 5 body is moving up with initial velocity lower than that of final velocity which gets accelerated. Therefore the acceleration is positive in this case.
Let us consider option 6,
In option 6 body is moving down with initial velocity lower than that of final velocity which gets accelerated. Therefore the acceleration is positive in this case.

Answer:
50 J
Explanation:
The net force acting on the box is given by the algebraic sum of the two forces, so:

The net work done on the box is equal to (assuming the net force is parallel to the displacement of the object)

where
F = 5 N is the net force on the object
d = 10 m is the displacement of the object
Substituting,
