need help with these 2 problems:
1. a horizontal force acting on a 3.0 kg object produces a horizontal acceleration of 6.0 m/s^2.find the magnitude of the net force acting on the object?

2. a force gives acceleration of 3m/s^2 to a 1kg body.if the same force accelerates another body at 9m/s^2, what is the mass of the second body?

1. 18 N
2. 1/3 kg...

anonymous · Answer

can u show me the formula on how did u get those answers?

anonymous · Answer

$$\Sigma F=ma$$
for a:
$$\Sigma F=3\times6=12 N$$

anonymous · Answer

how about the number 2 question?

anonymous · Answer

Find sigma F first with the same equation. What's sigma F?

anonymous · Answer

so u mean the one u gave formula to get $$\Sigma F$$?

anonymous · Answer

Yes, find sigma F now

anonymous · Answer

1/9 or .111 is the answer?

anonymous · Answer

sigma F=3*1=3 N
m=F/a=3/9=1/3
