Question

Find the resultant of two forces equal to 50 N and 30 N acting at an angle of 60°.​

Answer 1

Answer:

Resultant is 70N

Explanation:

a = 50N

b = 30N

$\alpha = 60 \: degree$

$R = \sqrt{ {a}^{2} + {b}^{2} + 2ab \cos( \alpha ) }$

$R = \sqrt{50(50) + 30(30) + 2(50)(30) \cos(60) }$

R = 70N
