Answer:
The correct solution will be "12.0 A".
Explanation:
The given values are:



By using the transformer formula, we get
⇒ 
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
The answer is 125 Joules
The first thing to take note of is the work equation: W=F×D
Since we already have our force and our distance that will help make this problem easier.
So, W=25*5
W=125
Therefore, our answer is 125 Joules since work is measured in joules
Hope this helped!! :)
Work is calculated by multiplying force by the distance that the object had moved. The applied force is 60 N, moving the object by 10 m. Thus, the work does is 600 J. For the friction force which is equal to,
100N x 0.250 = 25.0 N
the work done is,
W = (60 N - 25 N) x 10 m = 350 J
The kinetic energy of the box can be equated to this force. Thus, the answer is also 350 J.
