Question

Which would require greater force accelerating a 2kg mass at 5 m/s^2 or a 5 kg mass at 3 m/s^2

Answer 1

1 . FORCE= mass x acceleration  2 x 5 = 10 N   2.  FORCE=mass x acceleration  4 x 2 = 8 N   force of (1) is more  so (1)will require a greater force

Answer 2

5kg mass at 3m/s^2 would require more acclelerating
