A boy slides a book across the floor using a force of five and over a distance of 2M what is the kinetic energy of the book after he slides at assume there is no friction

Answer: 10Nm or 10J

Explanation:

Given the following:

Force (f) = 5

Distance (d) = 2m

Calculate the kinetic energy assuming no friction

Work done = force * distance

Work done = 5N * 2m = 10Nm

Recall:

Work done = ΔK. E (change in kinetic energy)

Therefore, kinetic energy of the book after sliding = ΔK. E, which is equal to work done.

Hence, K. E of book after sliding is 10Nm
