can't be simpler

F = ma = 8.5 x 2.8 = 23.8 N

a = F/m = 23.8 / 3 = 7.93 m/s²

PS: "m/s 2" is meaningless, I assumed you mean m/s²

Given,

Mass (m) = 8kg

Acceleration (a) = 2.8m/sec²

Force (F) = ?

We know that:-

Force (F) = Mass (m) x Acceleration (a)

Acceleration (a) = force (F) / Mass (m)

Now, force (F) = 8.5kg x 2.8m/sec²

= 23.8kg.m/sec² ≈ 24N

∴ force (F) = 24N
