Which would require a greater force accelerating a 2kg mass at 5 m/s -² or a 4 kg mass at 2 m/s-² ?

Which would require a greater force accelerating a 2kg mass at 5 m/s -

1.	Which would require a greater force accelerating a 2kg mass at 5 m/s -² or a 4 kg mass at 2 m/s-² ?
Answer» First of all we calculate the force of first:MASS=2kg ; Acc.=5m/s^2 ;Force=m × a 2 × 5=10kg.m/s^2;Force of 2=m × a = 4 × 2=8kg.m/s^2;Therefore greater force is required for acc. a 2kg mass at 5 m/s^2 ANS??? Can u do step by step 2kg at 5m/s becoz F=ma,2×5=10
