Answer:
-200 N
Explanation:
The cabinet moves at constant velocity, so that means there's no acceleration.
Applying Newton's second law to the cabinet:
∑F = ma
F + 200 = 0
F = -200
The friction force is 200 N in the opposite direction.
The law of conservation of energy states that energy is not created nor destroyed, rather it is only transferred or transmitted from one form to another. Now, the work exerted which is the input is only transformed to move the object which is now becomes the output work. Some are used to move the object, some are converted to other forms. That is why it is never greater than the input energy. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
