HELP!GIVING OUT MEDALS!
1.If a 40 kg person is accelerating at 10 m/s2, then the force acting on him or her is 400 N
A. true or B.false
2.How much force is needed to make a 60 kg object accelerate at a rate of 2.0 m/s2?
A. 62 N
B.62 kg
C.120 N
D.120 kg
3.What is the acceleration of a 30 kg object when 180 N of force is applied to it?
A.6.0 m/s2
B.60 m/s2
C.210 m/s2
D.5,400 m/s2
4.Which of the following equations show how you would solve for mass if you knew the force acting on an object & the acceleration of an object?
A.m=f/a
B.m= fa
C.m=a/f
D.m=f-a

Answer 1

in the first one...as F = MA
so yes force is 400 N

Answer 2

answer of second is C) 120N

Answer 3

and since F =MA
therefore A = F/M
so answer of third would be 180/30 = 18/3 = 6
i.e A

Answer 4

since F = MA
therefore
m = f/a

hence answer is a)... for the 4th question..
