if a ball is rolling down hill and accelerating at a rate of 2m/s^2 because of a 2N net force. What is the mass of the ball?

Step-by-step explanation:

According to Newton's second law

Force = mass * acceleration

Given

Force = 2N

acceleration = 2m/s^2

Mass =Force/Acceleration

Mass = 2/2

Mass =1kg

Hence the mass of the ball is 1kg

The answer is C) 2h + 1

First i factored out the negative sign, then i split the second term into two terms, then i factored out the common terms and i got -(h + 7) (2h + 1).
