Answer:
300 J
Explanation:
First of all, we need to calculate the net force acting on the crate, which is given by:
where
F = 100 N is the horizontal push
is the force of friction
Substituting,
Now we can calculate the net work done on the crate:
where
d = 10 m is the displacement
Substituting,
According to the work-energy theorem, the kinetic energy gained by the crate is equal to the work done on it: therefore, the answer is 300 J.
Explanation:
Since it is mentioned that the block is in equilibrium, this means the resultant force is zero, and all the forces cancel out each other.
You have to think it in a way so that, the forward force cancel out the backward force. Check the picture attached, on the forward side,
3N + 5N = 8N which cancel out the backward force of 8N
