v=3.5*2=7 m/s
Answer:
Explanation:
From the diagram affixed below completes the question
Now from the diagram; We need to resolve the force at point A into (3) components ; i.e x.y. & z directions which are equivalent to
So;
= positive x axis
Negative y axis
= positive z axis
Then;
From equation (1); Let's make the subject of the formula ; then :
Substituting the value for into equation (2) ; we have:
