A constant force F=6i+8j?6k moves an object along a straight line from point (6, 0, -10)...
Find the work done if the distance is measured in meters and the magnitude of the force is measured in newtons.
Homework Answers
Work Done = F.S
Here S = (-6i+7j+2k)-(6i+0j-10k)
= (6i+8j−6k) . (- 12i + 7j + 12k)
= -12*6 + 8*7 - 12*6
= 56 - 144
= - 88 J

1. A Constant force pushes an object and speeds it up. The object moves from (6i - 8j + 4k)m to (11i - 5j + 4k)m. The net force acting on the object is (2i + 4j + 5k)N. What is the increase in it's kinetic energy, in J? So I found in the x direction to be 10 J and in the y direction to be 12 J. I ignored the work in the k direction as the object...
