Explain the law of motion needed to solve thisproblem . On Planet Zorg, a 30 kg barbell can be lifted by only exerting a force fo 180N. What is the acceleration of gravity on Planet zorg? Predict how the motion of this object would change if on earth.
no
To solve this problem, we need to use Newton's Second Law of Motion. This law relates the force applied to an object, its mass, and the resulting acceleration.
Newton's Second Law of Motion states that the force (F) applied to an object is equal to the product of its mass (m) and acceleration (a), expressed as F = m * a.
In this case, we have a 30 kg barbell that can be lifted by exerting a force of 180 N on Planet Zorg. We need to find the acceleration of gravity on Planet Zorg. Let's denote the acceleration of gravity as 'g'.
Substituting the given values into Newton's Second Law, we have:
180 N = 30 kg * g
To find the value of 'g', we can rearrange the equation:
g = 180 N / 30 kg
By simplifying the right side of the equation, we get:
g = 6 N/kg
Therefore, the acceleration of gravity on Planet Zorg is 6 m/s².
Now, let's consider how the motion of this object would change if it were on Earth. On Earth, the acceleration due to gravity is approximately 9.8 m/s². Since the acceleration due to gravity on Planet Zorg is lower (6 m/s²), the barbell would feel lighter and the force required to lift it would be less compared to the situation on Earth.
In summary, to solve the problem, we used Newton's Second Law of Motion to find the acceleration of gravity on Planet Zorg and then analyzed how the motion of the object would differ if it were on Earth.
