Suppose your mass is 45 kg and the mass of your little brother is 25 kg. You push your brother +100 N and an equal but opposite force of -100 N is returned to you. Use the formula F=m/a to compute acceleration.

The work:

a= -100 N/45 kg

a= (-100 kg* m/s2)/45= -2 m/s2

So your acceleration is -2 m/s2

a= 100 N /25 kg

a= (100 kg* m/s2)/25 kg= 4 m/s2

So your little brother's acceleration is 4 m/s2

Thanks!
