Help, I am not sure I am doing this right. Are these correct?

Question

1.

What is the acceleration of a 1,500-kg elevator with a net force of 10,500 N?

2. What net force is needed to accelerate a 60-kg cart at 12 m/s 2? I think it is 720N

Answer 1

2 is right.

For 1, use the same f = ma you did in #2.
