Question

which wood required a greater force accelerating a 2 kilogram mass at 5 metre per second or a 4 kilogram mass at 2 metre per second ​

Answer 1

Answer:

Wood in 1st case will require greater force

Explanation:

1st case

M=2 kg

a=5 m/s^2

So, F=Ma=2×5 N =10N

2nd case

M=4kg

a=2 m/s^2

So F=Ma=4×2 N = 8N

M

Answer 2

$\huge\underline\mathrm{Solution-}$

First case :

m = 2 kg

a = 5 m $/{s}^{2}$

According to second law of motion

F = ma

F = $2 \times 5 = 10$ N

Second case :

m = 4 kg

a = 2 m $/{s}^{2}$

According to second law of motion

F = ma

F = $4 \times 2 = 8$ N

$\huge\underline\mathrm{Answer-}$

The wood in first case will require greater force
