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?

  • Physics -

    F=m*a
    F=5*4

    F=M*.8

    20=M*.8

  • Physics -

    So it's 20 x 0.8=16?

  • Physics -

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

    Oh! thanks!
    I understand it now :D
