Question

Which would require a greater force, accelerating a 3kg
mass at 5 m/s2 or a 5 kg at 4 m/s2 ?

Answer 1

Answer:

A 5 kg mass at

$4m{s}^{2}$

Explanation:

As,Force=Mass×Acceleration

Answer 2

Answer:

F= m×a

a1 =5m/s2

m1= 3kg

a2 = 4m/s2

m2=5kg

F1= a1×m1

F1 = 5×3=15N

F2= a2×m2

F2= 4×5=20 N

so,we can conclude that 5kg mass accelerating at 4m/s2 required greater force
