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.

AB = 10N
A=10+BEq 1
given
50=root A2+B2 its square
now square on both aise..
25000=(10+B)+ B2
2500=100+B2+20B +B2
B2+ 10B1200=0
B230B+40B1200=0
B(B30)+40(B30)=0
(B+40)(B30)=0
B=30 &
from eq 1
A =40
i hope soo u might be safistied with my answer. 
Its really the answer
