I've figured out how to do the FBD's and I think I've got it now, thanks for the help and sorry for being a bit thick ##F-mg=ma## ##F=mg+ma## ##F=m(g+a)## ##F=75(10+50)=4500N##

Ahhh I see Sorry for taking so long to get there! I appreciate the help

I'm not following, is it that the force being applied to the body is directly proportional to the acceleration acting on the body?

That I have a vertical acceleration of 4m/s^2?

Is this more accurate?

I'm not quite sure, would it be a sum of the true weight and the force caused by the body's mass and acceleration?

I'm sorry, I'm getting quite confused

Isn't weight the force acting on the mass of a body due to the gravitational attraction of the earth? Ah yes, maybe I should step back for a moment and learn how to properly do FBD's

I'm not sure what you mean by force balance equation But here is a rough free body diagram

I am not sure if I've added all the forces I need

I drew a free body diagram but I'm not sure if I did it correctly

Thank you, I'll have a look

My thinking was if I have a gravitational field strength of 10ms^-2 acting downwards and I also have an upwards acceleration of 1g (I think this is 10ms^2 in this context) acting in the opposite direction, they would cancel out? I have a feeling I'm making a big mistake here

Would it be the tension in the spring? Or the weight of the body?

75N?
