A force of 50 pounds acts on an object at an angle of 45 degrees. A second force of 75 pounds acts on the object at an angle of
Contact [7]

Answer:

The magnitude of the resultant force is:

R=100.3 \:pound

The direction is:

\theta=1.2^{\circ}

Step-by-step explanation:

Let's find the components of each vector is x and y-directions first.

<u>Sum of x-component vector forces.</u>

F_{tot-x}=F_{1}cos(45)+F_{2}cos(30)

F_{tot-x}=50cos(45)+75cos(30)

F_{tot-x}=100.3 \: pound

<u>Sum of y-component vector forces.</u>

F_{tot-y}=-F_{1}sin(45)+F_{2}sin(30)

F_{tot-y}=-50sin(45)+75sin(30)

F_{tot-y}=2.1 \: pound  

The magnitude of the resultant force is:

R=\sqrt{100.3^{2}+2.1^{2}}

R=100.3 \:pound

The direction is:

tan(\theta)=\frac{2.1}{100.3}

\theta=arctan(\frac{2.1}{100.3})

\theta=1.2^{\circ}

I hope it helps you!
