Answer:
The acceleration of each mass is the same, and approximately equal to 
Explanation:
Notice that the mass of the whole system is: 30 kg + 40 kg = 70 kg
If we use a net force of 100 N on the combined system, we can find the acceleration imparted to the masses via Newton's second law:

Explanation:
Assuming no air resistance, the horizontal acceleration at all points is 0, and the vertical acceleration at all points is -g (if near the surface of the Earth, -9.8 m/s²).
Explanation:
gravity is the force that acts between all objects
Answer:
Explanation:
I'm pretty sure the answer would be deductive reasoning. Deductive reasoning relies on making logical premises and basing a conclusion around those premises. It does not rely on making inferences and then assuming those inferences to be true.
