Which would require a greater force acceleration a 2kg mass at 5m/s*s or a 4kg mass at 2m/s*s
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...
Which would require a greater force accelerating at 2 kg mass at 5 metre per second or a 4 kg mass at 2 metre per second ?
