From Newton's second law (F=ma):
a = F/m = 189 N/30 kg = 6.0 m/s2
acceleration=force/mass use it u ll get acceleration on the planet
Explain the law of motion needed to solve this problem and then solve it. On Planet Zorg a 30 kg barbell can be lifted by only exerting a force of 180 N. What is the acceleration of gravity on Planet Zorg? Predict how the motion of this object would change if on Earth.
Is it the 2nd law of motion I don't understand how to find the motion would be on earth or on Zorg for that matter.

But does it change for Earth? Ok so I get that but do I change it for earth?
yes
