A box of mass 1kg is pulled through 1m along a level floor by a horizontal force of 8N. The box is then raised vertically onto a bench 2m high. If g=10m/s², calculate the total work done.
Answers
Answer:
SORRY NO IDEA!!
Explanation:
In a previous part of Lesson 1, work was described as taking place when a force acts upon an object to cause a displacement. When a force acts to cause an object to be displaced, three quantities must be known in order to calculate the work. Those three quantities are force, displacement and the angle between the force and the displacement. The work is subsequently calculated as force•displacement•cosine(theta) where theta is the angle between the force and the displacement vectors. In this part of Lesson 1, the concepts and mathematics of work will be applied in order to analyze a variety of physical situations.
