F = m a
205 - 196 = 80 a
is the horizontal force the same thing as net force.pls help
205 - 196 = 80 a
To find the acceleration of the hut, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
The formula for Newton's second law is:
F_net = m * a
where:
F_net is the net force,
m is the mass of the object, and
a is the acceleration.
In this case, you are given the mass of the hut as 80kg and the horizontal force as 205N. The magnitude of the force of friction is also given as 196N.
To find the acceleration, you need to calculate the net force acting on the hut. Since the force of friction acts in the opposite direction to the applied force, it will subtract from the applied force.
So, you can calculate the net force as:
F_net = applied force - force of friction
F_net = 205N - 196N
F_net = 9N
Now that you have the net force and the mass of the hut, you can find the acceleration using Newton's second law:
9N = 80kg * a
To solve for a, divide both sides of the equation by the mass of the hut (80kg):
a = 9N / 80kg
a ā 0.1125 m/sĀ²
Therefore, the acceleration of the hut is approximately 0.1125 m/sĀ².
