Not 100% sure though
Answer:
60 J
Explanation:
Given,
Work done to push the box = 100 J
Energy dissipated by friction = 40 J.
According to work energy theorem work done is equal to change in kinetic energy.
Change in Kinetic energy = Work done by student + Work done by friction
Change in Kinetic energy = 100 J - 40 J
Work done by the friction will be negative because it will act in opposite direction of force applied.
Change in Kinetic energy = 60 J
Answer:
material requirement planning
Explanation:
Material requirements planning (MRP) : This is a system for evaulating or calculating the materials and components needed to produce a product. This process consists of three primary steps taking which are inventory of the materials and components on hand, identifying which additional materials will be needed and finally scheduling their production or purchase.
