Explanation:
Given that, a hiker walls 9.4 miles at an angle of 60 degrees south of west. We need to find the west and south components of the walk.
From the attached figure, it is clear that, the west component of the walk is given by :
The south component of the walk is given by :
So, the west and south components of the walk are 4.7 miles and 8.14 miles respectively. Hence, this is the required solution.
Incomplete question as the angle between the force is not given I assumed angle of 55°.The complete question is here
Two forces, a vertical force of 22 lb and another of 16 lb, act on the same object. The angle between these forces is 55°. Find the magnitude and direction angle from the positive x-axis of the resultant force that acts on the object. (Round to one decimal places.)
Answer:
Resultant Force=33.8 lb
Angle=67.2°
Explanation:
Given data
Fa=22 lb
Fb=16 lb
Θ=55⁰
To find
(i) Resultant Force F
(ii)Angle α
Solution
First we need to represent the forces in vector form
Total Force
The Resultant Force is given as
For(ii) angle
We can find the angle bu using tanα=y/x
So
