Answer: The kinetic energy of the block increases by 15 Joules.
Explanation:
Work done is defined as the product of force and displacement of the object.
Mathematically,
[tex]W=F.s[/tex]
where,
W =work done
F = force
s = Displacement
Kinetic energy is defined as the energy which is possessed by the virtue of object's motion.
In the question, it is given that work done on block is 15 Joules and we need to find the change in kinetic energy of the block.
We know that,
Work done on the object = Change in kinetic energy of the object
Thus, Kinetic energy is increased by 15 Joules.
The kinetic energy depends on the work done by the applied force. The kinetic energy of the block increases by 15 J.
What is kinetic energy?
The energy possessed by an object by its motion is known as the object's kinetic energy.
Given data-
The magnitude of the constant horizontal force is F = 5 N.
The work done on the block is, W = 15 J.
As per the work-energy theorem, the work done by the applied force is equal to the change in kinetic energy.
Then,
W = ΔKE
Solving as
15 = ΔKE
ΔKE = 15 J
Thus, we can conclude that the block's kinetic energy increases by 15 J.
