Answer:
0.4Kg
Step-by-step explanation:
Marcus pulled the toy with a force of 22.0N and the cat pulled it in the opposite direction with 19.5N
=> F1= 22N
F2= -19.5N
Therefore the net force on the toy= F1+F2
Fnet =22-19.5
Fnet =2.5N
Force= Mass* Acceleration
2.5= (Mass)*6.25
=> Mass=2.5/6.25
=0.4Kg
Therefore the mass of the toy is 0.4Kg
