Answer:
a. when the acceleration of the objects become negative
Answer:
Explanation:
As the sum of the two right directed forces match exactly the left directed force, the only unbalanced force, and thus the net force, is the upward 25 N force.
The amount of force exerted is 77.7N
<u>Explanation:</u>
Given:
Work done, W = 350J
Distance, x = 4.5m
Force, F = ?
We know,
Work = force X distance
350 = F X 4.5m
F = 77.7N
Therefore, the amount of force exerted is 77.7N
