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.

Answer 1

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

given
50=root A2+B2 its square

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

i hope soo u might be safistied with my answer.

Answer 2

Its really the answer

Answer 3

yes,answer is correct

Answer 4

Thanks

Answer 5
