The required value of the change in kinetic energy during the given time interval is 32 J.
Given data:
The magnitude of force is, F = 8.00 N.
The time interval is, t = 12.0 s.
The distance covered by the block is, s = 4.00 m.
Here we can easily obtain the required result by applying the Work - Energy theorem. As per the work - energy theorem, the work done due to the applied force is equal to the change in kinetic energy.
Therefore,
W = ΔKE
And the work done is, W = Fs.
F× s = ΔKE
8.00 × 4.00 = ΔKE
ΔKE = 32 J
Thus, we can conclude that the required value of the change in kinetic energy during the given time interval is 32 J.
