Physics help finding m1 and m2?

by

Object 1 has a velocity V1 of 2 m/s x.

Object 2 has velocity V2 of 3.5 m/s y.

The total momentum has a magnitude of 17 and points in the direction 69 degrees above the x-axis.

Find m1 and m2.

I don’t even know where to start. Could someone work the problem through so I can understand. Once I see a problem done at least once I usually am able to understand it better.

  • Find the x and y components of the momentum

    Set the x momentum equal to the momentum of the x object

    Set the y momentum equal to the momentum of the y object

    x-momentum=17cos(69)=m1(2m/s)

    y-momentum=17sin(69)=m2(3.5m/s)

    solve for m1 and m2
