A certain force made a 5.0 kg mass accelerate at 4.0 m/s^2. This same force made another object accelerate at only 0.8 m/s^2. Find the mass of the second object.
I have no idea how to do this.
Do i use m=1/a? What do i do?

F=m*a
F=5*4
F=M*.8
20=M*.8

So it's 20 x 0.8=16?

20=M*.8
divide each side by .8
