100 Newtons.
Just apply Newton's Second Law.
-- The more mass an object has, the more gravitational force there is betweenit and the Earth.-- But the more mass an object has, the more force is required to accelerate it.-- The relationship between how much gravitational force there is and how much forceis required trades off just right, so that every mass has the same acceleration.
a sponge will have more matter packed in the same space
1kg of mass = 9.81 newtons 1kg = 9.81 newtons 1 newton = 0.101971621 kilogram-force 1 kilogram-force = 9.80665 newton Newton is not a unit of mass like the kilogram, it is a measure of force. A Newton is the amount of force that it takes to accelerate a mass at a rate of 1ms-2 The Earths gravity typically pulls 1kg. with a force of about 9.81N (N=Newton) but it varies a little depending where you are on Earth. So on Earth 0.102 Kg or 102 grams is one whole Newton
Force = mass x acceleration. I'll let you do the math.
Just apply Newton's Second Law.
force = mass x accel = 1800 x 3 = 5400 Newtons

Acceleration is not expressed in grams. A gram is a unit of mass. In any case, the upward force required is the sum of the helicopter's weight, and the force required to accelerate it. The weight is: w = mg (mass x gravity) The acceleration - once you decide how much it should accelerate upwards - can be found with Newton's Second Law. Once you calculate the two, just add them up.
It depends on the mass of the wall, and how fast you can accelerate the object you are using to break the wall. this is because Net Force (what you would need to break the wall) = mass times acceleration

Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.

You need two forces, which you simply add together: 1) The force required simply to support the weight. Multiply the mass times the gravity. 2) The force required to accelerate it. Find this force with Newton's Second Law. Then just add the two forces together.
