Answer:
The magnitude of the resultant force is
The direction of the resultant force is from the horizontal plane
Explanation:
Generally when resolving force, if the force (F )is moving toward the angle then the resolve force will be while if the force is moving away from the angle then the resolved force is
Now from the diagram let resolve the forces to their horizontal component
So
Now resolving these force into their vertical component can be mathematically evaluated as
Now the resultant force is mathematically evaluated as
substituting values
The direction of the resultant force is evaluated as
substituting values
from the horizontal plane
Answer:
Explanation:
The direction of the vector implies only its angle, not its magnitude. The direction of the vector is found in
so
but since we are in QII (where x is negative and y is positive) we have to add 180 to this number to get a direction of 165.5 degrees
Answer:
D
Explanation:
Beacuse the force got to the bottem first Meaning the andswer is D
