Question

Berapa resultan gaya A dan B jika gaya A = 5 N dan gaya B = 6 N?
1 N
8 N
√31 N
√91 N
10 N

Answer 1

Jawaban:

√91 N

Penjelasan:

diketahui:

F1 = A = 5N

F2 = B = 6N

rumus resultan gaya=

[tex] \sqrt{f1 ^{2}+{f2}^{2} + 2f1f2 \cos( \alpha ) } [/tex]

, maka:

=√ 5² +6² + 2 x 5 x 6 x cos 60° N

= √ 25 + 36 + 30 N

= √91 N
