i posted this earlier but got a confusing answer so pls help as best as u can asap!

True or False

1. If a 40 kg person is accelerating at 10 m/s2, then the magnitude of the force acting on him or her is 400 N.
(1 point)
true
false

Multiple Choice

2. How much force is needed to make a 60 kg object accelerate at a rate of 2.0 m/s2? (1 point)
62 N
62 kg
120 N
120 kg

3. What is the acceleration of a 30 kg object when 180 N of force is applied to it? (1 point)
6.0 m/s^2
60 m/s^2
210 m/s^2
5,400 m/s^2

4. Which of the following equations shows how you would solve for mass if you knew the force acting on an object and the acceleration of an object?
(1 point)
m = f/a
m = fa
m = a/f
m = f − a

soooooo need help!!! dunno what they are talking about! cant guess!
pls help asap!!!!!
thanx in advance

sry, im not that great at math even though this is science.

so the answers are
1. true
2. c
3. a
4. a
right...?

thanx Steve!:)

Thank you everyone.

1. True
2. C
3. A
4. A

TTR+s<3 is correct.

The answers R

1. True
2. C
3. A
4. A

1.True

2.C-120 N
3.A-6.0m/s2
4.A-m=f/a

This is all the same question, Newton's second law.

Force = mass * acceleration
THINK !!!

True, 3, 1, 1. I just took the test.

Thanks everyone for all your help!

YAY!

True,C,A,A
Is totally correct, thanks , and TTR+S<3

Thank everyone soooo much who helped to get the answers!!!! :) <3333

sry..... im actin real derpy right now

this is for 4. so the answer is b m=fa
kill me if i got that wrong
