Step-by-step explanation:
force 1 x distance 1= force 2 × distance 2
therefore 600n x 2m = 400n x distance 2
1200Nm = 400N x distance 2
1200Nm ÷ 400N = distance 2
the two netwons will cancel out each other so the answer is 3m
Answer:
2.1
Step-by-step explanation:
By the Law of Cosines,
a² = 5² + 6² - 2(5)(6)cos(20°)
a = sqrt(5² + 6² - 2(5)(6)cos(20°)), which is about 2.1
