Question

Which would require a greater force acceleration a 2 kg mass at 5 m s ^-2 or a 4 kg mass at 2 ms ^-2?

Answer 1

Answer:

F = Ma , so 2kg at 5 m/s^2

Explanation:

5*2 = 10 N

4*2 = 8 N

Answer 2

Answer:we have, Force F = ma

Explanation:Therefore, for the first mass, Force F1 =m1a1

= 2×5= 10N

And for the second mass, force F2 = m2a2

= 4×2=8N

Clearly, F1 > F2

Thus accelerating a 2 kg mass at 5ms^-2 would require a greater force.
