Question

Newton's second law states that the force produced by a moving object depends on its mass and acceleration. Which is an example of this? Two boulders move at the same rate of acceleration; the boulder with the smaller mass produces a greater force. Two boulders move at the same rate of acceleration; the boulder with the greater mass produces a greater force. A runner accelerates at a rate of 1 meter per second per second during a race.

Answer 1

Newton's second law is NOT talking about the force 'produced' by
a moving object. The law is saying that if you WANT to accelerate
that mass at that rate, then THAT's the force YOU'll have to apply
in order to accomplish the job.

The only choice that kind-of illustrates Newton's law is the last one.
The runner is able to deliver enough force from the muscles in his
legs to accelerate his own mass at the rate of 1 meter per second².
