Chapter 17, Problem 17.1EAA

To determine

Find the component of A=200 in the direction of B=100

Answer to Problem 17.1EAA

The component of A=200 in the direction of B=100 is $129°$

Explanation of Solution

Given Information:

Required information on finding the component of A=200 in the direction of B=100 is provided in the question

Component of A in the direction of B is $A\cos \theta$

  $\theta =30°+20°=50°$

  $\therefore A\cos \theta =200\cos 50$

  $=200\times 0.642=128.55\approx 129$

Conclusion:

The component of A=200 in the direction of B=100 is $129$
