A force of 31 N south is used to accelerate an object uniformly from rest to 8 m/s in 22 s. What is the mass of the object?

this question is centered around newtons second law f=ma

First you need to find the acceleration

that gives you 0.36 recurring(on both numbers) m/s²

mass= force ÷ acceleration

mass= 85.25 kg

if you want to check

f=ma

85.25 × 0.36 recurring (remember its on both numbers not just 6) = 31 N

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
