The first is that the object moves. The second is that a force must act on the object in the direction the object moves.
Answer:
F = 5
Explanation:
F = m x v^2/r = 2 x 10^2/5 =200/5 = 40 (N)
By definition, we have that the work done is given by:

Where,
F: force in the direction of displacement
d: displaced distance
Substituting values we have:

Then, the power is given by:

Where,
t: time
Substituting values we have:


Answer:
The work done on the box is 100 Nm, and the power is 20 Nm/s.
