Question

Which has a higher acceleration a 10-kg object acted upon with a net force of 20 N or an 18-kg object acted on by a net force of 30 N?

Answer 1

First object:
m=10 kg
F=20 N

F=ma, then:
a=F/m
a=20/10=2 m/s²

Second object:
m=18 kg
F=30 N

a=F/m
a=30/18=1.6 m/s²

The first object has a higher acceleration.
