How fast would a bird move in the air if it were flying with a speed of 50 m/h directly into a strong wind of 50 m/h?
a) 50 m/h
b) 100 m/h
c) 0 m/h*
What is the resultant of a 6 N east force pushing on an object and a 8 N force acting on an object at the same time?
For that question it require typing so no multiple choice.
1st one looks good
2nd one needs the direction of the 8 N force
I forgot to add 8 N west sorry
the resultant is a 2 N force to the west
To determine the speed of the bird in the air, we need to consider the effect of the wind. If the bird is flying directly into a strong wind, the wind speed would act as a resistance force, reducing the bird's speed relative to the ground.
To find the bird's speed, we need to calculate the resultant of the bird's flying speed and the wind's speed. In this case, the bird is flying with a speed of 50 m/h directly into a strong wind with a speed of 50 m/h.
To find the resultant, we need to subtract the wind speed from the bird's flying speed because they are acting in opposite directions.
So, the resultant speed of the bird in the air would be:
50 m/h - 50 m/h = 0 m/h
Therefore, the bird's speed in the air would be 0 m/h. Hence, the correct answer is option c) 0 m/h.

To determine the resultant of the two forces, we need to consider their magnitudes and directions.
First, we have a 6 N eastward force acting on the object. This means the force is pulling or pushing the object towards the east direction.
Second, we have an 8 N force acting on the object. However, the direction of this force is not specified in the question, so we'll consider all possible directions.
If the 8 N force is also eastward, then to find the resultant force, we add the magnitudes of the two forces since they are acting in the same direction:
6 N + 8 N = 14 N
In this case, the resultant force would be 14 N eastward.
If the 8 N force is westward, then we subtract the magnitudes of the two forces since they are acting in opposite directions:
8 N - 6 N = 2 N
In this case, the resultant force would be 2 N westward.
If the 8 N force is acting in a direction other than east or west, we would need to analyze the vectors using vector addition techniques such as the parallelogram or triangle method.
Without more information about the direction of the 8 N force, we cannot determine the exact resultant force.
