Aconstant force of f = 47i + 30j moves an object along a vector d = 13i - 8j, where units are in pounds and feet. find the work done.

The work is  371 lb ft

Explanation:

The work can be calculated with yhe scalar product between the force and the displacement:

The scalar product is obtained multiplying component to comoponent and summing the terms:

= <47, 30> · <13, -8>  [lb ft]

= 47*13  + 30*(-8) [lb ft]

Finally:

W = 371 [lb ft]

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
