f^2 + 2f = f (f + 2)
2f + 8 = 103 2f = 95 f = 47.5
the resultant magnitude is 2 times the magnitude of F as the two forces are equal, Resultant R= F + F = 2F and the magnitude of 2F is 2F.
F=3S (a father is 3 times as old as his son) F+15=2(S+15) (after 15 years the father will be twice as old as his sons age at that time) F/3=S F+15=2(F/3+15) F+15=2(F/3)+2(15) F+15=(2F)/3+30 F+15(-15)=(2F)/3+30(-15) F=(2F)/3+15 F(3)=(2F)/3+15)(3) 3F=2F+45 3F(-2F)=2F+45(-2F) F=45
2f! :/
2f + 8 = 102 Subtract 8 from both sides: 2f = 94 Divide both sides by 2: f = 47
2f
face to face
F = m aa = F/mThe acceleration of (2F) acting on (4m) is ( 2F/4m ) = (2/4) (F/m) = (2/4) a = 1/2 a
2f
2F = -16.7 degrees Celsius.
