Aperson is trying to lift a crate that has a mass of 30 kg. the normal force of the floor is currently supplying 150n of force. how much force is the person currently exerting?

Here when an object is placed on the level floor then in that case there are two forces on the object

1). Weight of object downwards (mg)

2). Normal force due to floor which will counterbalance the weight (N)

so when no force is applied on the box at that time normal force is counter balanced by weight.

Now here it is given that A person tried to lift the box upwards

So now there are two forces on the box

1). Applied force of person

2). Normal force due to ground

So now these two forces will counter balance the weight of the crate

So we can write an equation for force balance like

given that

here

m = 30 kg and

g = acceleration due to gravity = 10 m/s^2

now from above equation

So force applied by the person must be 150 N

tube or goog will be great resources to find the answer to the question that you're asking

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt
