The part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life
I’m assuming the cannon ball is being shot directly horizontally. If there’s an angle, this answer will be wrong. But either way, you want to use Newton’s Second Law of motion.
F = ma, you could change this to a = F/m to get a better understanding of the equation. Acceleration and force are directly proportional. The mass is inversely proportional to acceleration. This means the net force will be in the same direction as the acceleration.
Alright back to the problem:
F = 4kg*110m/s^2
F = 440N
Potential energy. It is energy that has the potential to become kinetic (moving).
Hey!
The correct answer is A.1. We know this because any good and controlled experiment will only be successful if one thing and one thing only changes. If there were two or more variables changing, then it’d be hard to collect accurate data and correct/confirm the hypothesis.
I hope I helped!
