Question

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?

Answer 1

1kg

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
