Two parallel forces of magnitude 4 and 6 newton are acting on a body placed at 4m apart. Resultant force will be

1250

Here S=44m V=42m/s U=? a=3m/s² Now we know that 2as=v²-u² 2(3)(44)=(42)²-u² u=10√15m/s

Sum of two natural consecutive no. is77 & g.c.d is 7 then find other pairs.

60×2=40×V So, (60×20)/-40=-3M/S Therefore v=-3M/S

Very good
