Question

) Which would require a greater force accelerating a 5 kg mass at 5 ms^-2
or a 3 kg mass at 7 ms^-2?​

Answer 1

Answer:

Force F=ma

(1) : F1 =m1 a 1

=2×5=10 N

(2) : F 2=m 2 a 2

=4×2=8 N

So, 2 kg will require greater force.

Answer 2

Answer:

5 kg mass at 5m^-2

Explanation:

as force is equal to mass ×acceleration

5×5=25N and 3×7=21 N

as 25N>21N

1st option is correct
