F = ma
Force (in Newtons) equals mass (in kilograms) times acceleration (in meters per second squared)
In this case, 450 = 30a, so the accelerating is 15 meters per second squared
The acceleration can be calculated using the formula a = F/m, where F is the force applied and m is the mass of the object. Plugging in the values, a = 450 N / 30 kg, the acceleration will be 15 m/s^2.
If an object has a mass of 30 kg, its mass on Earth would also be 30 kg. Mass is a measure of the amount of matter in an object, and it remains the same regardless of the gravitational force acting on it.
What you mean to say is: "The net force acting on the ball is 30 N."F = M AA = F / M = (30) / (4) = 7.5 m/s2
The force of gravity acting on an object on the moon is about 1/6th of that on Earth. Therefore, the force of gravity acting on an object with a mass of 180kg on the moon would be approximately 180kg * 1/6 = 30kg.
For an object experiencing a constant net force, Newton's Second Law of Motion can be used to obtain the equationF = ma,where F is the net force, m is the mass of the object and a is the acceleration of the object due to the net force, F. Rearranging the equation for acceleration and substituting in the mass of the box and the net force acting on it givesa = 900N/300kga = 3ms-2.

30kg = 30kg.
3 tenths of 30kg = 3/10 * 30kg = 9kg
The mass is physical quantity measured in kilograms, and the weight is a force measured in Newtons.The weight depends on the mass of the planet you are standing on, and altitude. At sea level on earth, 1 kg presses on a scale with 9.8 Newtons of force, 30kg with 294 Newtons, but the scale shows 1kg or 30kg respectively for weight because we tend to think of mass and weight as synonymous.A very precise spring scale is going to show lower weight at higher altitudes! In orbit, the weight is zero; even though the mass is the same! Because of this variation with altitude, scales that must measure mass accurately do not depend on springs.
The weight of the girl on Earth would be approximately 294.3 Newtons (N) since weight is the force of gravity acting on an object's mass. This is calculated by multiplying the mass of the girl (30 kg) by the acceleration due to gravity on Earth (9.81 m/s^2).
30kg is equal to approximately 66 pounds.
