Two forces acting on a body in opposite directions,have the resultant velocities of 10newton. if they act at right angles to each other, the resultant is 50 newton.find the two forces.

  • physics - ,

    A-B = 10N
    A=10+B-----Eq 1

    50=root A2+B2 its square

    now square on both aise..
    25000=(10+B)+ B2
    2500=100+B2+20B +B2
    B2+ 10B-1200=0
    B=30 &
    from eq 1
    A =40

    i hope soo u might be safistied with my answer.
