Question

25N -> 20N ->
<- friction 3n

What is the net force

42n left
45n right
42n right
48n right

Answer 1

To find the net force, we can start by breaking down the information given:

1. There is a 25 N force to the right.
2. A 20 N force is also applied to the right.
3. Friction is acting to the left at 3 N.

Now, we can calculate the net force as follows:

- Total force to the right: 25 N + 20 N = 45 N
- Force acting to the left (friction): 3 N

Now, to get the net force, we subtract the leftward force from the total rightward force:

\[
\text{Net Force} = \text{Total Right Force} - \text{Friction}
\]
\[
\text{Net Force} = 45 N - 3 N = 42 N
\]

So, the net force is 42 N to the right.

Therefore, the answer is **42 N right**.
