Find the net force and the acceleration for the situation below.
30N 20N
<---------------[ 5.1kg]---------->
F = m a
Would it not be easier to do the problem than to type it here?
To find the net force and acceleration for the given situation, we need to consider Newton's second law of motion. According to this law, the net force (F_net) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). Mathematically, it can be represented as:
F_net = m * a
Given:
Mass (m) = 5.1 kg
Force A (30N) is pointing to the left.
Force B (20N) is pointing to the right.
To find the net force, we need to consider the direction of the forces. Since force A is in the opposite direction of force B, we can subtract them to find the net force:
Net Force (F_net) = 30N - 20N = 10N to the left.
Now, we can calculate the acceleration using the formula mentioned above. Rearranging the formula, we get:
a = F_net / m
Substituting the values:
a = 10N / 5.1kg = 1.96 m/s^2
Therefore, the net force is 10N to the left, and the acceleration is 1.96 m/s^2.
