Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magn
bearhunter [10]

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

F_1 = 45

F_2 = 50

\theta = 33

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)

This gives:

R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)

R^2 = 2025+ 2500 - 4500* 0.8387

R^2 = 2025+ 2500 - 3774.15

R^2 = 750.85

Take square roots of both sides

R = \sqrt{750.85\\

R = 27.40
