which would require a greater force-- accelerating a 10g mass at 5m/s² or a 20g mass at 2m/s²?

$\huge\red{Answer}$

We find that F1>F2, hence more force is required to accelerate a 10 g mass at 5ms−2, than accelerating a 20 g mass at 2ms−2.

Answer 2

Question :

which would require a greater force ---- accelerating a 10g mass at 5m/s² or a 20g mass at 2m/s²?

Answer :

Case 1 :

Force, f = mass ✖ acceleration

$\frac{10}{1000} kg \times 2m \: per \: s {}^{2} \\ 0.05 \: n$

Case 2 :

Force, f = mass ✖ acceleration

$\frac{20}{1000} kg \: \times 2m \: per \: s {}^{2} \\ 0.04 \: n$

Thus, a greater force of 0.05 N is required for accelerating a 10 g mass.
