Question

1. Which would require a greater force - accelerating a 2 kg mass at
5 ms? or at 5 kg mass at 3 ms??
(according to class 9
with give and step by step explanation) ​

Answer 1

Explanation:

∴F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton. =6N. Therefore, Force required to accelerate the body is 6N.

Answer 2

YOUR ANSWER IS ACCELERATING A 2Kg MASS AT 5m/s^2 would require a greater force.

Force   F=ma

Force   F=ma(1) :    F1=m1a1=2×5=10 N

Force   F=ma(1) :    F1=m1a1=2×5=10 N(2) :   F2=m2a2=4×2=8 N

Force   F=ma(1) :    F1=m1a1=2×5=10 N(2) :   F2=m2a2=4×2=8 NSo, 2 kg will require greater force.
