Question

Which one would require a greater force -- accelerating a 2 kg mass at 5 m/s2

or

a 4 kg mass at 2 m/s2 ?​

Answer 1

Answer:

2 kg mass will reuire greater force

Explanation:

Force   F=ma

(1) :    F1=m1a1=2×5=10 N [m1= 2kg, a1= 5 m/s2]

(2) :   F2=m2a2=4×2=8 N [m2= 4kg, a2= 2m/s2]

Or, F1 > F2

so, 2 kg will reuire greater force.
