two girls exeret a force of 30 N and 10 N on a bag in same direction. a dog tugs at bag and drag it in oppsite direction with the force of 5 N. calculate the new force exerted on bag and draw a vector diagram.
F= 10+30 = 40 N
dog applied force in opposite direction with 5 N
40N - 5N = 35 N
yes
vector diagram...?

To calculate the new force exerted on the bag, we first need to find the total force exerted on the bag by the two girls. Since the two girls are exerting forces of 30 N and 10 N in the same direction, we can simply add the two forces together.
Total force exerted by the two girls = 30 N + 10 N = 40 N
Next, we need to account for the dog tugging on the bag in the opposite direction with a force of 5 N. To find the new force exerted on the bag, we subtract the force exerted by the dog from the total force exerted by the two girls.
New force exerted on the bag = 40 N - 5 N = 35 N
Therefore, the new force exerted on the bag is 35 N.
Now let's draw a vector diagram to represent the forces involved:
30 N (girl 1)
-------------------------->
------>
10 N (girl 2)
<------
<-------------------------
5 N (dog)
In the vector diagram, the arrows represent the forces exerted on the bag. The arrow pointing to the right represents the force of 30 N exerted by girl 1, the arrow pointing to the left represents the force of 10 N exerted by girl 2, and the arrow pointing to the left represents the force of 5 N exerted by the dog.
The total resultant force (new force exerted on the bag) is obtained by subtracting the force of 5 N from the sum of the forces exerted by the two girls.
