The resultant of four forces is 1000 N in the direction 30° west of North. Three forces are 400 N, 60° North of East,200 N south and 400 N 53° west of south. The rectangular components of the fourth force are ??

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
